TC, CASE TEMPERATURE (°C)

Figure 8. 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 6 is based on TC = 25°C; TJ(pk) is vari-

able 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 der-

ate the same as thermal limitations. Allowable current at the

voltages shown on Figure 6 may be found at any case tem-

perature by using the appropriate curve on Figure 8.

At high case temperatures, thermal limitations will reduce

the power that can be handled to values less than the limita-

tions imposed by second breakdown.

Use of reverse biased safe operating area data (Figure 7)

is discussed in the applications information section.
