Note 1. V_BR measured after I_T applied for 300us, I_T=square wave pulse or equivalent
2. Surge current waveform per Fig. 3 and derated per Fig. 2
3. For bi-directional types having V_RWM of 10 volts and less, the I_R limit is doubled
4. Suffix ‘C’ denotes bi-directional devices. Suffix ‘A’ denotes 5% tolerance devices, no suffix denotes 10% tolerance devices.
5. All terms and symbols are consistent with ANS/IEEE C62.35
