The single unidirectional channel protects a single 43.6V nominal rail against inductive load dumps and ISO 7637-2 transients common in automotive 24V systems. The package footprint is standard for the 1.5SMC series, allowing direct drop-in replacement for other 1500W TVS diodes in the same case. Supplied on Tape & Reel, the part is ready for automated pick-and-place assembly. No power line protection is provided — this is a signal or low-power rail clamp, not a mains input protector. Sourcing is through authorized distribution channels and independent surplus inventory. The date-code and lot traceability are maintained — the laser etch on the DO-214AB body should match Vishay's plant and week code format for the procurement lot.","metaTitle":"1.5SMC51AHM3/I Vishay TVS, 1500W, 43.6V, DO-214AB","metaDescription":"Vishay 1.5SMC51AHM3/I Zener TVS diode, 1500W peak pulse, 43.6V reverse standoff, AEC-Q101 automotive grade.

The 1.5SMC series from Vishay includes the base part 1.5SMC51A (non-automotive grade) — the HM3/I suffix denotes AEC-Q101 qualification.
