Product details

Unidirectional clamping at 70 V standoff

The 1.5SMCJ70CA-AQ: Rated 1.5 kW peak pulse power means it absorbs the transient energy without going into thermal runaway — this is the rating that sizes the downstream protection zone in an automotive ECU input or power rail.

Automotive temperature grade in SMC package

Surface-mount SMC/DO-214AB package fits the standard land pattern; the component engineer should verify the cathode bar orientation matches the unidirectional polarity — this part clamps in one direction only (Power Line Protection: No).
