Breakdown Voltage
VBR
(Volts) (Note 1)
Notes:
1. VBR measured after IT applied for 300us, IT =square wave pulse or equivalent.
2. Surge current waveform per Figure 3 and derate per Figure 2.
3. For bipolar types having VWM of 10 volts and under, the ID limit is doubled.
4. All terms and symbols are consistent with ANSI/IEEE C62.35.
