Product details

AEC-Q101 automotive grade — deployment context

The 1.5SMC56AHM3_A/H: The unidirectional single-channel configuration protects a single signal or supply rail; the TransZorb® die construction delivers the clamping speed needed for fast transients like load-dump and inductive kickback.

DO-214AB SMC — board integration checklist

No power line protection rating — this is a signal-line TVS, not a mains-rated protector; use it on DC rails and data lines where the 47.8 V standoff fits the operating voltage.
