The protection window is defined by three voltage levels: reverse standoff of 214 V (the rail voltage below which the diode is effectively off), breakdown minimum of 237 V (where conduction begins), and clamping maximum of 344 V at rated current. For a 214 V bus, this provides a 23 V margin before the diode starts conducting, and limits the transient to 344 V — well within the typical 400 V rating of downstream semiconductors. The supplier device package is listed as DO-214AB (SMCJ), confirming interchangeability with the common SMCJ footprint. The tape-and-reel packaging (TR suffix) indicates the part ships on 13-inch reels suitable for automated pick-and-place assembly. No power line protection is claimed — this is a general-purpose transient suppressor for signal and DC power rails, not for AC mains primary protection. ## Active lifecycle and sourcing The base product number 1.5SMC250 covers the full family; the -M3/57T suffix denotes the specific packaging and environmental rating variant.","metaTitle":"Vishay 1.5SMC250A-M3/57T TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC250A-M3/57T Zener TVS diode, 1500W peak pulse power, 214V standoff, 344V clamping.
