NOTES: 1.

Normal selection criteria for TVS devices is by rated stand-off voltage (VWM) and should be equal or greater than dc or continuous peak

operating voltage.

2.

TVS devices are tested to maximum peak pulse current (IPP) 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 (e.e., 1.5KE33C or 1.5KE33CA). For Bidirectional types having VWM of 8 volts and

under, the ID leakage current is doubled. 1N62XX or 1N5908 not available as Bidirectional. For Bipolar capacitance will be .5 that shown in

Fig. 2 for zero bias.

4.

For unidirectional, the forward voltage (VF) is 3.5 volts maximum at 100 Amps peak for 8.3 ms half-sine wave.
