dissipated in the transistor while in avalanche must be less
than the rated limit and adjusted for operating conditions
differing from those specified. Although industry practice is
to rate in terms of energy, avalanche energy capability is not
a constant. The energy rating decreases non−linearly with an
increase of peak current in avalanche and peak junction
temperature.
