The copper pad area under the cathode tab sets the junction-to-ambient thermal resistance — for a 1500W 10/1000µs pulse, the standard 1 oz copper pad on FR-4 keeps the junction rise within the 150°C limit. Tape & Reel packaging supports automated pick-and-place. No pin-compatible second-source is listed, but the 1.5SMC series covers the same footprint with different standoff voltages if the protection threshold needs adjustment.","metaTitle":"1.5SMC540AHE3_AIH Vishay TVS, 1500W, 459V Standoff, AEC-Q101","metaDescription":"Vishay 1.5SMC540AHE3_AIH Zener TVS diode, 1500W peak pulse, 459V reverse standoff, 740V clamping, DO-214AB SMC, AEC-Q101 automotive qualified.","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","Series":"Automotive, AEC-Q101, 1.5SMC, TransZorb®","Package":"Tape & Reel (TR)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC540","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)":"513V","Voltage - Clamping (Max) @ Ipp":"740V","Voltage - Reverse Standoff (Typ)":"459V","Current - Peak Pulse (10/1000µs)":"2.03A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC540AHE3_AIH/alternatives.json"},"ai":{"faq":[{"question":"What is the 1.5SMC540AHE3_AIH used for?","answer":"It protects 459V DC rails from voltage transients up to 740V clamping. Typical applications include automotive 24V and 48V power distribution, battery management systems, and motor drive circuits where load-dump or inductive kickback can exceed the rail voltage. The AEC-Q101 grade ensures it survives the under-hood thermal cycle."},{"question":"What compliance documentation is available for this part?","answer":"As an AEC-Q101 qualified device, Vishay provides production-part approval process (PPAP) documentation, RoHS compliance data, and material declaration sheets on request.
