There are two limitations on the power handling ability of a transistor: average junction temperature and second breakdown. Safe operating area curves indicate IC − VC − V− 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) = 150�C; TCJ(pk) = 150�C; TC = 150�C; TC�C; TCC; TCC 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 150�C. At high case temperatures, thermal limitations�C. At high case temperatures, thermal limitationsC. At high case temperatures, thermal limitations will reduce the power that can be handled to values less then the limitations imposed by second breakdown.
