Product details

1500W peak pulse — the surge rating that sets the protection class

The 1.5SMC15CAHE3_A/H: The 12.8 V reverse standoff voltage means the diode stays transparent to the protected rail under normal operation, only conducting when the transient exceeds the 14.3 V minimum breakdown threshold.

AEC-Q101 automotive grade — the qualification that governs deployment

The -65°C to 150°C junction temperature range covers the full automotive thermal profile, from cold-crank to engine-bay soak.

Bidirectional single-channel — one device for symmetrical protection

Housed in the standard DO-214AB (SMC) surface-mount package, the footprint matches the industry SMCJ suffix parts, simplifying board layout reuse across similar TVS ratings.
