SECOND BREAKDOWN LIMIT

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 Figures 12 and 13 is based on TC = 25_C;

TJ(pk) is variable depending on power level. Second break-

down pulse limits are valid for duty cycles to 10% but must be

derated for temperature according to Figure 1.
