Figure 4. Temperature Coefficients
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.
The data of Figure 3 is based on T_J(pk) = 150_C; T_C is
variable depending on conditions. Second breakdown pulse
limits are valid for duty cycles to 10% provided T_J(pk)
v 150_C. At high case temperatures, thermal limitations
will reduce the power that can be handled to values less than
the limitations imposed by second breakdown.
