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

verse voltage conditions. Calculations of TJ therefore must include forward and reverse power effects. The allowable operating

TJ may be calculated from the equation: TJ = TJmax − r(t)(Pf + Pr) where

r(t) = thermal impedance under given conditions,

Pf = forward power dissipation, and

Pr = reverse power dissipation

This graph displays the derated allowable TJ due to reverse bias under DC conditions only and is calculated as TJ = TJmax − r(t)Pr,

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