There are two limitations on the power handling ability of
a transistor: average junction temperature and second
breakdown. Safe operating area curves indicate I
C
– V
CE
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.

is
variable depending on power level. Second breakdown
pulse limits are valid for duty cycles to 10% but must be
derated for temperature.
