Derating Per Leg *
* 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.
