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.
