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; 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

limitations imposed by secondary breakdown.
