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 lim-
its of the transistor that must be observed for reliable opera-
tion; i.e., the transistor must not be subjected to greater
dissipation than the curves indicate.

is variable depending on conditions. Second breakdown
tpulse limits are valid for duty cycles to 10% provided TJ(pk)
150 _C. TJ(pk) may be calculated from the data in
Figure 4. At high case temperature, thermal limitations will
reduce the power that can be handled to values less than the
limitations imposed by second breakdown.
