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
