Notes:
1. V
BR
measure after I
T
applied for 300us, I
T
=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 through SMBJ170
5. For bipolar types having V
WM
of 10 volts(SMBJ8.0C) and under, the I
D
limit is doubled.
