Typical Operating Temperature Derating* * 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. 70 75 80 85 90 95 105 110 115 120 RqJA = 25.6°C/W 400 °C/W 324.9 °C/W 235 °C/W 130 °C/W 10 26 18 14 200 300 400 Figure 9.
