a transistor; average junction temperature and secondary
breakdown. Safe operating area curves indicate I
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.
There are two limitations on the power handling ability of
