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 15 is
based on T
level. Second breakdown pulse limits are valid for duty
cycles to 10% but must be derated when T
breakdown limitations do not derate the same as thermal
limitations. Allowable current at the voltages shown in
Figure 15 may be found at any case temperature by using the
appropriate curve on Figure 17. T
from the data in Figure 20 and 21. At any case temperatures,
thermal limitations will reduce the power that can be handled
to values less than 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.
