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 the curves indicate.
The data of Figure - 2 and Figure - 3 is based on TJ(PK) = 150°C;
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 limitation will
reduce the power that can be handled to values less than the
limitations imposed by second breakdown.
