Suffix ‘C’ denotes Bi-directional device. Suffix ‘A’ denotes 5% tolerance device, no suffix denotes a 10% tolerance device.

1. For Bi-directional devices having VR of 10 volts and below, the IR limit is doubled.

2. VF = 3.5 Volts max. for devices of VR <100v, and VF = 5.0 Volts max for devices of VR >100V. IF = 100A, 300 µS square wave.
