Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits
are exceeded, device functional operation is not implied, damage may occur
and reliability may be affected.

2. TOLERANCE AND TYPE NUMBER DESIGNATION The type numbers listed indicate a tolerance of
5%.
3. ZENER VOLTAGE (V
Z
) MEASUREMENT
Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature at 25
C.
4. ZENER IMPEDANCE (Z
Z
) DERIVATION Z
ZT
and Z
ZK
are measured by dividing the ac voltage drop across the device by the ac current
applied. The specified limits are for I
Z(ac)
= 0.1 I
Z(dc)
with the ac frequency = 60 Hz.
