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 5 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)
v 150°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.
