, DERATED OPERATING TEMPERATURE ( C)
J

* Reverse power dissipation and the possibility of thermal runaway must be considered when operating this device under any
reverse 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: T
J
= T
Jmax
− 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 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.
