It is qualified to AEC-Q101, making it suitable for automotive-grade applications where reliability under temperature extremes and surge events is required. The reverse standoff voltage is 33.3 V, providing margin for 24 V or 28 V DC rails. Breakdown voltage is guaranteed at a minimum of 37.1 V, ensuring the TVS begins conducting before the protected circuitry sees an overvoltage condition. The single unidirectional channel means polarity must be observed on DC lines. The wide range also supports high-reliability designs where ambient temperature may exceed 85°C.","metaTitle":"Vishay 1.5SMC39AHE3/57T TVS, 1500W, 33.3V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC39AHE3/57T Zener TVS diode, 1500W peak pulse, 33.3V standoff, AEC-Q101 automotive qualified, 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":"1.5SMC39","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)":"37.1V","Voltage - Clamping (Max) @ Ipp":"53.9V","Voltage - Reverse Standoff (Typ)":"33.3V","Current - Peak Pulse (10/1000µs)":"27.8A"}},"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/1.5SMC39AHE3%2F57T/alternatives.json"},"ai":{"faq":[{"question":"What automotive qualification does 1.5SMC39AHE3/57T carry?","answer":"It is AEC-Q101 qualified, which certifies the device for automotive-grade reliability, including temperature cycling, ESD, and extended temperature range testing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC39AHE3-57T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC39AHE3-57T when reusing this data.
