DEVICES FOR BIDIRECTION APPLICATIONS
For bidirectional devices use CA suffix (e.g. SM15T12CA). Electrical characteristics apply in both directions.
APPLICATION NOTES
A 1500 W (SMC) device is normally selected when the threat of transients is from lightning induced transients, conducted via external leads or I/O lines. It is also used to protect against switching transients induced by large coils or industrial motors. Source impedance at component level in a system is usually high enough to limit the current within the peak pulse current (IPP) rating of this series. In an overstress condition, the failure mode is a short circuit.
