Notes:
1. VBR measured after IT applied for 300us, IT= sequare wave pulse or equivalent.
2. Surge current waveform per 10 x 1000us exponential wave and derated per Fig.2.
3. All terms and symbols are consistent with ANSI/IEEE C62.35.
4. For bi-directional types having V
RWM
of 10 volts and less, the I
R
limit is doubled
