The clamping voltage ceiling of 12.1V at peak pulse current is what the downstream circuit sees, so the protected rail must tolerate a 12.1V spike riding on top of the nominal rail before the TVS turns on at 7.79V minimum breakdown. The reverse standoff of 7.02V typ is the working voltage below which the TVS appears high-impedance — the protected rail sits cleanly below breakdown in normal operation. This makes it suited for 5V and 6V nominal rails that need headroom to 7V without false triggering. ## Sourcing — active, available to order Listed Active by Vishay General Semiconductor — Diodes Division. Available in Tape & Reel and Cut Tape packaging for production and rework alike.","metaTitle":"Vishay 1.5SMC8.2A-E3/57T TVS Diode, 1500W, 7.02V standoff","metaDescription":"Vishay 1.5SMC8.2A-E3/57T unidirectional TVS diode, 1500W peak pulse, 7.02V standoff, 12.1V clamping.

The TransZorb construction gives repeatable breakdown voltage and low leakage current compared to a plain Zener, making it the right choice when you need guaranteed clamping performance rather than just voltage regulation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC8.2A-E3-57T","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/1.5SMC8.2A-E3-57T when reusing this data.
