1. Normal selection criteria fro TVS devices is by rated stand-off voltage (V
WM
) and should be equal or greater than dc or continuous peak
operating voltage.
2. TVS devices are tested to maximum peak pulse current (l
PP
) with clamping voltage monitored. This surge capability is one of the most significant electrical
characteristics of the device and should be considered as part of customer quality inspections.
3. For Bidirectional part number add C or CA as suffix. For Bidirectional types having V
WM
of 8 volts and under, the l
D
leakage current is doubled. For bipolar
capacitance will be .5 that shown in Fig. 2 for zero bias.
4. For unidirectional, the forward voltage (V
F
) is 3.5 volts maximum at 100 Amps peak 8.3 ms half-sine wave.
