SECOND BREAKDOWN
DERATING
There are two limitations on the power handling ability of
a transistor: average junction temperature and second
breakdown. Safe operating area curves indicate I
C
V
CE
limits of the transistor that must be observed for reliable
operation; i.e., the transistor must not be subjected to greater
dissipation than the curves indicate.
The data of Figure 7 is based on T
C
= 25
_C; T
J(pk)
is
variable depending on power level. Second breakdown
pulse limits are valid for duty cycles to 10% but must be
derated when T
C
25
_C. Second breakdown limitations do
not derate the same as thermal limitations. Allowable
current at the voltages shown on Figure 7 may be found at
any case temperature by using the appropriate curve on
Figure 9.
T
J(pk)
may be calculated from the data in Figure 10. At
high case temperatures, thermal limitations will reduce the
power that can be handled to values less than the limitations
imposed by second breakdown.
