Figure 1. 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 then the curves indicate.

The data of Figure 1 is based on TJ(pk) TC is variable depending on conditions. Second breakdown pulse limits are valid for duty cycles to 10% provided TJ(pk) 150_C. At high case temperatures, thermal limitations will reduce the power that can be handled to values less then the limitations imposed by second breakdown.
