For a 24V system, this provides a 50V+ margin above the worst-case steady-state voltage, preventing nuisance triggering from normal ripple. ## Automotive qualification and operating envelope for under-hood and chassis environments No power-line protection feature is built in — this is a pure clamping device for signal or low-power supply rails. ## Active production and sourcing for BOM placement The lifecycle status is Active, meaning Vishay continues to manufacture this part without a planned end-of-life notification. As a single-channel unidirectional device in the 1.5SMC family, the 1.5SMC510AHM3_B/H is a drop-in fit for designs requiring a 434V standoff TVS in the DO-214AB footprint. No pin-compatible successor or second-source is recorded on this order code.","metaTitle":"Vishay 1.5SMC510AHM3_B/H Zener TVS, 1500W, 434V, AEC-Q101","metaDescription":"Vishay 1.5SMC510AHM3_B/H Zener TVS diode, 1500W peak pulse power, 434V reverse standoff, AEC-Q101 automotive grade, DO-214AB package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Grade":"Automotive","Series":"1.5SMC, TransZorb®","Package":"Tape & Reel (TR)","Applications":"-","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC510","Operating Temperature":"-65°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"485V","Voltage - Clamping (Max) @ Ipp":"698V","Voltage - Reverse Standoff (Typ)":"434V","Current - Peak Pulse (10/1000µs)":"2.15A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6058","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC510AHM3_B%2FH/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does Vishay provide for this TVS diode?","answer":"The part carries AEC-Q101 automotive qualification.
