For automotive 12 V and 24 V rails the standoff and clamping figures are the two numbers that govern part selection. Reverse standoff of 70.1 V typ is the voltage the TVS sees in normal operation without conducting — the rail must sit below this in the unclamped state. When a transient exceeds the breakdown minimum of 77.9 V, the Zener Avalanche junction turns on and the clamping voltage of 113 V at 13.3 A peak pulse is what reaches the downstream load. The 13.3 A peak pulse rating is specific to the 10/1000 µs wave shape; a faster risetime pulse or a higher-energy surge at the same current will produce a higher clamping voltage because the Zener's dynamic resistance is not zero. ## Active status and sourcing posture The base product number 1.5SMC82 identifies the series family; alternative 1.5SMC82 variants in the same series share the same pinout and footprint but differ in standoff voltage — verify the 70.1 V standoff and 77.9 V minimum breakdown match your rail before specifying. Quoted to order against BOM quantity; availability and current lead times confirmed at RFQ.","metaTitle":"Vishay 1.5SMC82AHE3/57T, 1.5kW TVS Zener, DO-214AB","metaDescription":"Vishay 1.5SMC82AHE3/57T unidirectional TVS Zener, 70.1V standoff, 113V clamping, 1.5kW peak pulse, AEC-Q101, DO-214AB SMC.","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":"1.5SMC82","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)":"77.9V","Voltage - Clamping (Max) @ Ipp":"113V","Voltage - Reverse Standoff (Typ)":"70.1V","Current - Peak Pulse (10/1000µs)":"13.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC82AHE3-57T","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/1.5SMC82AHE3-57T when reusing this data.
