Tj = 25 °C - 100 µA I (1) R Reverse leakage current VR = VRRM Tj = 125 °C - 5 15 mA Tj = 125 °C IF = 7.5 A - 0.5 0.57 V (1) F Forward voltage drop Tj = 25 °C IF = 15 A - 0.84 V Tj = 125 °C IF = 15 A - 0.65 0.72
Notes:
(1)Pulse test: tp = 380 µs, δ < 2% To evaluate the conduction losses use the following equation: P = 0.42 x I 2 F(AV) + 0.020 IF (RMS) 2/14 DocID3516 Rev 8
