Product details

Active production — what it means for your BOM

The 1.5SMC18A-M3/9AT: The 15.3V reverse standoff voltage means it stays transparent on a 12V or 15V rail and only starts conducting when the transient exceeds the 17.1V minimum breakdown threshold.

Package and temperature envelope

Housed in a DO-214AB (SMC) surface-mount package, the same footprint as the SMCJ series. Single unidirectional channel — one device protects one rail. Rated for general-purpose transient suppression with no power-line protection (not intended for AC mains clamping).
