Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. Rev.O 1/5 LESHAN RADIO COMPANY, LTD.

Typical Operating Temperature Derating* r(t), TRANSIENT THERMAL RESISTANCE * Reverse power dissipation and the possibility of thermal runaway must be considered when operating this device under any reverse 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 D = 0.5 100 0.2 0.1 0.05 P(pk) 10 0.01 t1 t2 DUTY CYCLE, D = t1/t2 1 SINGLE PULSE qJA = 321.8 °C/W Test Type > Min Pad < Die Size 38x38 @ 75% mils 0.1 0.000001 0.00001 0.0001 0.001 0.01 0.1 1 10 100 1000 t1, TIME (sec) Figure 9.
