Figure 5. Active Region Safe Operating Area
There are two limitations on the power handling ability of a
transistor: average junction temperature and second break-
down. 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 dissipa-
tion 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
vlimits 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 temperatures, thermal limitations will
reduce the power that can be handled to values less than the
limitations imposed by second breakdown.
