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 be observed for reliable

operation; i.e., the transistor must not be subjected to greater

dissipation than the curves indicate.

The data of Figures 5 and 6 are based on TJ(pk) = 150_C;

TC is variable depending on conditions. Second breakdown

pulse limits are valid for duty cycles to 10% provided TJ(pk)

< 150

_C. TJ(pk) may be calculated from the data in Figure 4.

At high case temperatures, thermal limitations will reduce

the power that can be handled to values less than the

limitations imposed by second breakdown.
