SECOND BREAKDOWN LIMITATION
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 lim-
its of the transistor that must be observed for reliable opera-
tions e.g., the transistor must not be subjected to greater
dissipation than the curves indicate.
At high case temperatures, thermal limitations will reduce
the power that can be handled to values less than the limita-
tions imposed by secondary breakdown.
