Note: Non ‘A’ devices have higher clamping voltage. Add suffix ‘C’ to denote bi-polar devices. VBR max not quoted.
1. For Bi-directional devices having VR of 10 volts and below, the IR limit is doubled.
2. For Uni-directional devices VF = 3.5 Volts max at IF = 50A, 300 µS square wave pulse. * Preferred voltages.
