Transil average power dissipation

In repetitive operation, the specification to be considered is mean power.

Equation 2

(ƒ: frequency, W: energy dissipated at each pulse)

The junction temperature calculated from this power should never exceed the specified

maximum junction temperature. This temperature is calculated from the thermal resistance,

exactly like for a diode.
