It mounts surface-mount in the DO-214AB (SMC) package and is shipped on Tape & Reel for automated assembly. General-purpose classification means it suits consumer, industrial, and communications board-level protection roles — not a dedicated automotive or safety-rated grade without supplemental qualification. ## What the peak pulse ratings mean for your protection circuit This 1.5 kW ceiling is the primary sizing parameter — the clamping voltage of 12.1 V max at Ipp is what actually appears across the protected node when the peak pulse current of 124 A flows through the device during a surge event. The absence of a power-line protection flag tells you this is a board-rail suppressor, not a mains-front-end clamp: keep it downstream of the input filtering stage where it clamps residual differential spikes the upstream MOV or gas tube did not catch. ## Sourcing posture — active lifecycle, no last-time-buy on record marks this part Active — no NRND flag, no EOL notice, no last-time-buy window. The 1.5SMC series is a long-running Vishay line and the 1.5SMC8.2A variant is a standard 8.2 V working-voltage clamp, not a specialty or newly obsoleted variant. Sourced to order through independent distribution; availability and lot-level pricing confirmed at RFQ.","metaTitle":"1.5SMC8.2A-M3/57T — Vishay 1.5kW Zener TVS, DO-214AB SMC","metaDescription":"Vishay 1.5SMC8.2A-M3/57T Zener Transient Voltage Suppressor (TransZorb®), 1500W peak pulse, 12.1V clamping, 124A Ipp, 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":"1.5SMC, TransZorb®","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC8.2","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)":"7.79V","Voltage - Clamping (Max) @ Ipp":"12.1V","Voltage - Reverse Standoff (Typ)":"7.02V","Current - Peak Pulse (10/1000µs)":"124A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3333","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC8.2A-M3%2F57T/alternatives.json"},"ai":{"faq":[{"question":"Is there a pin-compatible alternative in the 1.5SMC family?","answer":"The 1.5SMC series shares a common DO-214AB footprint and pinout across voltage variants — a different 1.5SMCxxA with the same 1.5 kW peak pulse rating and SMC package is mechanically and electrically compatible on the board.
