In a 85°C under-hood environment, the derating factor is roughly 60%, so the effective pulse-handling capacity drops to about 900W. Unidirectional (single-channel) Zener construction — the cathode is the tab side of the SMC package. This is the right polarity for positive-rail clamping; for bidirectional or AC-coupled lines, a different variant in the 1.5SMC family would be needed. ## Automotive grade and compliance RoHS compliance is standard for the Vishay TransZorb series; no separate compliance document is needed beyond the standard Vishay material declaration.","metaTitle":"Vishay 1.5SMC56AHE3/57T TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC56AHE3/57T Zener TVS diode, 1500W peak pulse, 47.8V standoff, 77V clamp, AEC-Q101 automotive grade, DO-214AB SMC 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","Series":"Automotive, AEC-Q101, 1.5SMC, TransZorb®","Package":"Tape & Reel (TR)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC56","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)":"53.2V","Voltage - Clamping (Max) @ Ipp":"77V","Voltage - Reverse Standoff (Typ)":"47.8V","Current - Peak Pulse (10/1000µs)":"19.5A"}},"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/1.5SMC56AHE3%2F57T/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative in the 1.5SMC family?","answer":"The 1.5SMC56A (non-automotive) is the same die in the same DO-214AB package, but lacks AEC-Q101 qualification.
