Note 1:

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 TJ(pk) = 150_C; TC is

variable depending on conditions. Second breakdown pulse

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

v 150_C. At high case temperatures, thermal limitations

will reduce the power that can be handled to values less than

the limitations imposed by second breakdown.
