There are two limitations on the power handling ability of

a transistor: average junction temperature and second

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.

variable depending on power level. Second breakdown

pulse limits are valid for duty cycles to 10% but must be

derated for temperature.
