There are two limitation on the power 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 curves indicate. The data of curve is base 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 less than the limitations imposed by second breakdown.
