Peak Repetitive Forward Current, (Square Wave, 20 kHz, TC = 168C) Non-Repetitive Peak Surge Current (Surge Applied at Rated Load Conditions Halfwave, Single Phase, 60 Hz) Peak Repetitive Reverse Surge Current (2.0 ms, 1.0 kHz) Storage Temperature Range Operating Junction Temperature (Note 1) Voltage Rate of Change (Rated VR)
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. The heat generated must be less than the thermal conductivity from Junction-to-Ambient: dPD/dTJ < 1/RqJA.
