Darlington Transistors

FIGURE - 6 ACTIVE REGION 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 not be

subjected to greater dissipation than the curves indicate.

The data of Figure - 6 is based on TJ(PK) = 150°C;Tc is variable

depending on power level. Second breakdown pulse limits are valid for

duty cycles to 10% provided TJ(PK) ≤150°C, At high case

temperatures, thermal limitation will reduce the power that can be

handled to values less than the limitations imposed by second

breakdown.
