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 curves indicate.

The data of SOA curve is base on Tj (PK) = 150°C; Tc is variable

depending on conditions. At high case temperatures, thermal limitation

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

limitations imposed by second breakdown
