VCE, COLLECTOR±EMITTER VOLTAGE (VOLTS)
Figure 1. Rated Forward Biased
Safe±Operating Area
There are two limitations on the power handling ability of a transistor: average junction temperature and second breakdown. 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 dissipation than the curves indicate.
The data of Figure 1 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%.
TJ(pk) may be calculated from the data in Figure 6. At high case temperatures thermal limitations will reduce the power
that can be handled to values less than the limitations imposed by second breakdown.
