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 (I_PP)
rating of this series. In an overstress condition, the
failure mode is a short circuit.
TYPICAL APPLICATIONS
Use in sensitive electronics protection against voltage
transients induced by inductive load switching and
lighting on ICs, MOSFET, signal lines of sensor units
for consumer, computer, industrial, automotive and
telecommunication.
