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 Figures 5, 6 and 7 is based on TJ(pk) = 200_C; TC is variable depending on conditions. Second breakdown pulse
limits are valid for duty cycles to 10% provided TJ(pk) < 200_C. TJ(pk) may be calculated from the data in Figure 4. At high case
temperatures, thermal limitations will reduce the power that can be handled to values less than the limitations imposed by
second breakdown.
