Product details

Automotive-grade transient protection

The 1.5SMC200AHM3_A/I: It is intended for transient suppression on 12 V and 24 V vehicle power buses, telecom line cards, and industrial DC rails where 171 V standoff is the nominal working voltage. The DO-214AB (SMC) package footprint is industry-standard; the copper pad area under the cathode tab sets the thermal resistance for sustained pulse handling. No power line protection is built in — this is a unidirectional transient clamp, not a crowbar or filter.

Sourcing and compliance

Base product number is 1.5SMC200; this specific suffix (AHM3_A/I) denotes the AEC-Q101 automotive grade and the lead-free, RoHS-compliant termination finish. No official second-source or pin-compatible alternative is recorded in this listing.
