Operating Area
Figure 17. Forward Bias Power Derating
There are two limitations on the power handling ability of a
transistor: average junction temperature and second break-
down. Safe operating area curves indicate IC–VCE limits of
the transistor that must be observed for reliable operation;
i.e., the transistor must not be subjected to greater dissipa-
tion than the curves indicate. The data of Figure 15 is based
on TC = 25
°
C; TJ(pk) is variable depending on power level.
Second breakdown pulse limits are valid for duty cycles to
10% but must be derated when TC
≥
25
°
C. Second
breakdown limitations do not derate the same as thermal
limitations. Allowable current at the voltages shown on Figure
15 may be found at any case temperature by using the
appropriate curve on Figure 17. TJ(pk) may be calculated
from the data in Figures 20 and 21. At any case tempera-
tures, thermal limitations will reduce the power that can be
handled to values less the limitations imposed by second
breakdown. For inductive loads, high voltage and current
must be sustained simultaneously during turn–off with the
base–to–emitter junction reverse biased. The safe level is
specified as a reverse–biased safe operating area (Figure
16). This rating is verified under clamped conditions so that
the device is never subjected to an avalanche mode.
