Notes:
1. VBR measure after IT applied for 30ms, IT=square wave pulse or equivalent.
2. Surge current waveform per Figure. 3 and derate per Figure. 2.
3. All terms and symbols are consistent with ANSI/IEEE C62.35.
4. For bidirectional use C or CA suffix for types SMBJ5.0 - SMBJ170
5. For bipolar types having VWM of 10 V (SMBJ8.0C) and under, the ID limit is doubled.
