* Reverse power dissipation and the possibility of thermal runaway must be considered when operating this device under any re-

r(t) = thermal impedance under given conditions,

Pf = forward power dissipation, and

Pr = reverse power dissipation

where r(t) = Rthja. For other power applications further calculations must be performed.
