* 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. 1000 ANCE D = 0.5 100 0.2 0.1 0.05 10 P(pk) 0.01 t1 t2 1 DUTY CYCLE, D = t1/t2 SINGLE PULSE Test Type > Min Pad < Die Size 38x38 @ 75% mils qJA = 321.8 °C/W 0.1 r(t), TRANSIENT THERMAL RESIST 0.000001 0.00001 0.0001 0.001 0.01 0.1 1 10 100 1000 t1, TIME (sec)
