*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

This graph displays the derated allowable T
r(t)Pr, where r(t) = Rthja. For other power applications further calculations must be performed.
