SMC-package TVS diodes at this power class rely on the PCB pad geometry and copper area around the cathode tab to conduct heat away from the junction; check the Vishay thermal resistance curve in the datasheet for your layout before committing to a derating margin. ## Thermal envelope and the design headroom question The -65 °C low end covers cold-start and outdoor equipment deployment without derating concerns; the limiting factor is always the high side when the device is absorbing transients in a thermally constrained enclosure.","metaTitle":"Vishay 1.5SMC6.8CA-M3/57T TVS Diode, 10.5V Clamping","metaDescription":"Vishay 1.5SMC6.8CA-M3/57T Zener TVS, 1500W peak pulse, 5.8V standoff, DO-214AB SMC.

Lead time and pricing are verified with each quote; independent distribution carries the series and can usually confirm availability against BOM quantities within days of an enquiry."},{"question":"What does \"TransZorb®\" mean — is this a Zener or a TVS diode?","answer":"Vishay's TransZorb® is the company's trademarked TVS (transient voltage suppressor) design, built on Zener avalanche technology — it behaves as a bidirectional clamping device that activates at the breakdown voltage during transients. It carries a Zener-type specification (6.45 V minimum breakdown) but functions as a TVS in the circuit, protecting against voltage spikes rather than regulating a supply rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC6.8CA-M3-57T","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/1.5SMC6.8CA-M3-57T when reusing this data.
