MJW3281A (NPN) MJW1302A (PNP)
There are two limitations on the power handling ability of
a transistor; average junction temperature and secondary
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 Figures 13 and 14 is based on TJ(pk) = 150°C;
TC is variable depending on conditions. At high case
temperatures, thermal limitations will reduce the power than
can be handled to values less than the limitations imposed by
second breakdown.
