- Parameter Reverse leakage current Tests Conditions VR = 300 V Tj = 25°C Tj = 125°C VF
- - Forward voltage drop IF = 40 A Tj = 25°C Tj = 125°C Pulse test :
- tp = 5 ms, δ < 2 %
- - tp = 380 µs, δ < 2% To evaluate the maximum conduction losses use the following equation : P = 0.75 x IF(AV) + 0.0062 IF(RMS)2 0.85 80 Min. Typ. Max. 80 800 1.25 1 V Unit µA
