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.
Polarity: for unidirectional types the band denotes cathode
end, no marking on bidirectional types
