* Reverse power dissipation and the possibility of thermal runaway must be considered when operating this device under any re-
verse voltage conditions. Calculations of T J therefore must include forward and reverse power effects. The allowable operating
T J may be calculated from the equation:
This graph displays the derated allowable T J due to reverse bias under DC conditions only and is calculated as T J = T Jmax − r(t)Pr,
where r(t) = Rthja. For other power applications further calculations must be performed.
