APPLICATION NOTE -- ZENER VOLTAGE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tion temperature under any set of operating conditions in order
to calculate its value. The following procedure is recom-
mended:
Lead Temperature, TL, should be determined from:
TL =
LAPD + TA.
LA is the lead-to-ambient thermal resistance (
C/W) and PD is
the power dissipation. The value for
LA will vary and depends
on the device mounting method.
LA is generally 30 to 40
C/W
for the various clips and tie points in common use and for
printed circuit board wiring.
The temperature of the lead can also be measured using a
thermocouple placed on the lead as close as possible to the tie
point. The thermal mass connected to the tie point is normally
large enough so that it will not significantly respond to heat
surges generated in the diode as a result of pulsed operation
once steady-state conditions are achieved. Using the mea-
sured value of TL, the junction temperature may be deter-
mined by:
TJ = TL +
TJL.
TJL is the increase in junction temperature above the lead
temperature and may be found from Figure 2 for dc power:
TJL =
JLPD.
For worst-case design, using expected limits of IZ, limits of
PD and the extremes of TJ(
TJ) may be estimated. Changes in
voltage, VZ, can then be found from:
V =
VZTJ.
VZ, the zener voltage temperature coefficient, is found from
Figures 4 and 5.
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zener resistance. For best regulation, keep current excursions
as low as possible.
Surge limitations are given in Figure 7. They are lower than
would be expected by considering only junction temperature,
as current crowding effects cause temperatures to be ex-
tremely high in small spots, resulting in device degradation
should the limits of Figure 7 be exceeded.

NOTE 3. ZENER IMPEDANCE (ZZ) DERIVATION
ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current
applied. The specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 60 Hz.
NOTE 4. MAXIMUM ZENER CURRENT RATINGS (IZM)
Values shown are based on the JEDEC rating of 400 mW. Where the actual zener voltage
(VZ) is known at the operating point, the maximum zener current may be increased and is
limited by the derating curve.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
Tolerance designation -- Device tolerances of
5% are indicated by a "B" suffix,
2% by a
"C" suffix,
1% by a "D" suffix.
NOTE 2.
This data was calculated using nominal voltages. The maximum current handling capability
on a worst case basis is limited by the actual zener voltage at the operating point and the pow-
er derating curve.
NOTE 3.
ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current
applied. The specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 1.0 kHz.
NOTE 4.
Nominal Zener Voltage (VZ) is measured with the device junction in thermal equilibrium at the
lead temperature of 30
C
1
C and 3/8
lead length.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
The type numbers shown have a standard tolerance of
5% on the nominal zener voltage.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal Zener Voltage is measured with the device junction in the thermal equilibrium with
ambient temperature of 25
C.
NOTE 3. ZENER IMPEDANCE (ZZT) DERIVATION
The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-
rent having an rms value equal to 10% of the dc zener current (IZT) is superimposed on IZT.
NOTE 4. MAXIMUM ZENER CURRENT RATINGS (IZM)
Maximum zener current ratings are based on maximum zener voltage of the individual units.
NOTE 5. REVERSE LEAKAGE CURRENT IR
Reverse leakage currents are guaranteed and are measured at VR as shown on the table.
NOTE 6. SPECIAL SELECTORS AVAILABLE INCLUDE:
A) Tighter voltage tolerances. Contact your nearest Motorola representative for more infor-
mation.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
The "B" suffix type numbers listed are
5% tolerance of nominal VZ.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal zener voltage is measured with the device junction in thermal equilibrium with ambi-
ent temperature of 25
C.
NOTE 3. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current
having an rms value equal to 10% of the dc zener current (IZT) is superimposed on IZT.
NOTE 4. REVERSE LEAKAGE CURRENT IR
Reverse leakage currents are guaranteed and are measured at VR as shown on the table.
NOTE 5. MAXIMUM REGULATOR CURRENT (IZM)
The maximum current shown is based on the maximum voltage of a
5% type unit, therefore,
it applies only to the "B" suffix device. The actual IZM for any device may not exceed the value
of 400 milliwatts divided by the actual VZ of the device.
NOTE 6. MAXIMUM REGULATION FACTOR (
VZ)
VZ is the maximum difference between VZ at IZT and VZ at IZL measured with the device
junction in thermal equilibrium.

APPLICATION NOTE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tion temperature under any set of operating conditions in order
to calculate its value. The following procedure is recom-
mended:
Lead Temperature, TL, should be determined from:
TL =
LAPD + TA.
LA is the lead-to-ambient thermal resistance (
C/W) and PD is
the power dissipation. The value for
LA will vary and depends
on the device mounting method.
LA is generally 30 to 40
C/W
for the various clips and tie points in common use and for
printed circuit board wiring.
The temperature of the lead can also be measured using a
thermocouple placed on the lead as close as possible to the tie
point. The thermal mass connected to the tie point is normally
large enough so that it will not significantly respond to heat
surges generated in the diode as a result of pulsed operation
once steady-state conditions are achieved. Using the mea-
sured value of TL, the junction temperature may be deter-
mined by:
TJ = TL +
TJL.
TJL is the increase in junction temperature above the lead
temperature and may be found as follows:
TJL =
JLPD.
JL may be determined from Figure 3 for dc power condi-
tions. For worst-case design, using expected limits of IZ, limits
of PD and the extremes of TJ(
TJ) may be estimated. Changes
in voltage, VZ, can then be found from:
V =
VZ
TJ.
VZ, the zener voltage temperature coefficient, is found from
Figure 2.
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zener resistance. For best regulation, keep current excursions
as low as possible.
Surge limitations are given in Figure 5. They are lower than
would be expected by considering only junction temperature,
as current crowding effects cause temperatures to be ex-
tremely high in small spots, resulting in device degradation
should the limits of Figure 5 be exceeded.

*Indicates JEDEC Registered Data.
NOTE 1. TOLERANCE AND TYPE NUMBER DESIGNATION
The JEDEC type numbers listed have a standard tolerance on the nominal zener voltage of
5%. C for
2%, D for
1%.
NOTE 2. SPECIALS AVAILABLE INCLUDE:
Nominal zener voltages between the voltages shown and tighter voltage tolerances.
For detailed information on price, availability, and delivery, contact your nearest Motorola rep-
resentative.
NOTE 3. ZENER VOLTAGE (VZ) MEASUREMENT
Motorola guarantees the zener voltage when measured at 90 seconds while maintaining the
lead temperature (TL) at 30
C
1
C, 3/8
from the diode body.
NOTE 4. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-
rent having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed
on IZT or IZK.
NOTE 5. SURGE CURRENT (ir) NON-REPETITIVE
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, re-
verse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second dura-
tion superimposed on the test current, IZT, per JEDEC registration; however, actual device
capability is as described in Figure 5 of the General Data -- DO-41 Glass.

APPLICATION NOTE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tion temperature under any set of operating conditions in order
to calculate its value. The following procedure is recom-
mended:
Lead Temperature, TL, should be determined from:
TL =
LA PD + TA
LA is the lead-to-ambient thermal resistance (
C/W) and
PD is the power dissipation. The value for
LA will vary and
depends on the device mounting method.
LA is generally
3040
C/W for the various clips and tie points in common
use and for printed circuit board wiring.
The temperature of the lead can also be measured using a
thermocouple placed on the lead as close as possible to the tie
point. The thermal mass connected to the tie point is normally
large enough so that it will not significantly respond to heat
surges generated in the diode as a result of pulsed operation
once steady-state conditions are achieved. Using the mea-
sured value of TL, the junction temperature may be deter-
mined by:
TJ = TL +
TJL
TJL is the increase in junction temperature above the lead
temperature and may be found from Figure 2 for a train of
power pulses (L = 3/8 inch) or from Figure 10 for dc power.
TJL =
JL PD
For worst-case design, using expected limits of IZ, limits of
PD and the extremes of TJ (
TJ) may be estimated. Changes
in voltage, VZ, can then be found from:
V =
VZ
TJ
VZ, the zener voltage temperature coefficient, is found from
Figures 5 and 6.
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zener resistance. For best regulation, keep current excursions
as low as possible.
Data of Figure 2 should not be used to compute surge capa-
bility. Surge limitations are given in Figure 3. They are lower
than would be expected by considering only junction tempera-
ture, as current crowding effects cause temperatures to be ex-
tremely high in small spots resulting in device degradation
should the limits of Figure 3 be exceeded.

NOTE 4. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-
rent having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed
on IZT or IZK.

NOTE 1. TOLERANCES
Suffix 5 indicates 5% tolerance. Any other tolerance will be considered as a special device.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
Motorola guarantees the zener voltage when measured at 40 ms
10 ms 3/8
from the diode
body, and an ambient temperature of 25
C (+8
C, 2
C)
NOTE 3. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-
rent having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed
on IZT or IZK.
NOTE 4. SURGE CURRENT (ir) NON-REPETITIVE
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, re-
verse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second dura-
tion superimposed on the test current, IZT, per JEDEC standards, however, actual device ca-
pability is as described in Figure 3 of General Data sheet for Surmetic 30s.
NOTE 5. SPECIAL SELECTIONS AVAILABLE INCLUDE:
Nominal zener voltages between those shown. Tight voltage tolerances such as
1% and
2%. Consult factory.

NOTE 1. TOLERANCE AND TYPE NUMBER DESIGNATION
The JEDEC type numbers shown indicate a tolerance of
5%.
NOTE 2. ZENER VOLTAGE (VZ) AND IMPEDANCE (ZZT & ZZK)
Test conditions for zener voltage and impedance are as follows: IZ is applied 40
10 ms prior
to reading. Mounting contacts are located 3/8
to 1/2
from the inside edge of mounting clips
to the body of the diode. (TA = 25
C +8, 2
C).
NOTE 3. SURGE CURRENT (ir)
Surge current is specified as the maximum allowable peak, non-recurrent square-wave cur-
rent with a pulse width, PW, of 8.3 ms. The data given in Figure 6 may be used to find the
maximum surge current for a square wave of any pulse width between 1ms and 1000 ms by
plotting the applicable points on logarithmic paper. Examples of this, using the 3.3 V and
200 V zeners, are shown in Figure 7. Mounting contact located as specified in Note 3. (TA =
25
C +8, 2
C.)
NOTE 4. VOLTAGE REGULATION (
VZ)
Test conditions for voltage regulation are as follows: VZ measurements are made at 10% and
then at 50% of the IZ max value listed in the electrical characteristics table. The test current
time duration for each VZ measurement is 40
10 ms. (TA = 25
C +8, 2
C). Mounting contact
located as specified in Note 2.
NOTE 5. MAXIMUM REGULATOR CURRENT (IZM)
The maximum current shown is based on the maximum voltage of a 5% type unit, therefore,
it applies only to the B-suffix device. The actual IZM for any device may not exceed the value
of 5 watts divided by the actual VZ of the device. TL = 75
C at 3/8
maximum from the device
body.
NOTE 6. SPECIALS AVAILABLE INCLUDE:
Nominal zener voltages between the voltages shown and tighter voltage tolerance such as
1% and
2%. Consult factory.

APPLICATION NOTE
Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc-
tion temperature under any set of operating conditions in order
to calculate its value. The following procedure is recom-
mended:
Lead Temperature, TL, should be determined from:
TL =
LA PD + TA
LA is the lead-to-ambient thermal resistance and PD is the
power dissipation.
Junction Temperature, TJ, may be found from:
TJ = TL +
TJL
TJL is the increase in junction temperature above the lead
temperature and may be found from Figure 4 for a train of
power pulses or from Figure 5 for dc power.
TJL =
JL PD
For worst-case design, using expected limits of IZ, limits of
PD and the extremes of TJ (
TJ) may be estimated. Changes
in voltage, VZ, can then be found from:
V =
VZ
TJ
VZ, the zener voltage temperature coefficient, is found from
Figures 2 and 3.
Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zener resistance. For best regulation, keep current excursions
as low as possible.
Data of Figure 4 should not be used to compute surge capa-
bility. Surge limitations are given in Figure 6. They are lower
than would be expected by considering only junction tempera-
ture, as current crowding effects cause temperatures to be ex-
tremely high in small spots resulting in device degradation
should the limits of Figure 6 be exceeded.
