That 10.5 V clamp is the figure that matters most in practice: when a surge hits, the diode clamps the protected rail below 10.5 V and dissipates up to 1500 W peak, preventing the downstream IC from seeing the overvoltage spike. The CA suffix designates bidirectional polarity — the diode clamps both polarities, so it sits across a single-ended rail without needing two opposing unidirectional devices. ## DO-214AB SMC footprint and assembly context The part ships in the DO-214AB (SMCJ) package on Tape & Reel, rated for surface-mount pick-and-place. The wide operating junction temperature range of -65 °C to 150 °C covers the full industrial envelope — from unheated warehouse storage through to equipment mounted in thermally aggressive enclosures. Note the spec explicitly lists Power Line Protection as \"No\" — this is a general-purpose TVS for signal-line or secondary rail clamping, not a primary AC mains protection device. The part carries an Active lifecycle status from Vishay General Semiconductor — Diodes Division, so it is in regular production and suitable for new designs without a last-time-buy countdown. Availability and lead time confirmed at RFQ.","metaTitle":"Vishay 1.5SMC6.8CA-M3/9AT TVS Diode, 1500W, 10.5V clamp","metaDescription":"Vishay 1.5SMC6.8CA-M3/9AT bidirectional TVS diode, 5.8V standoff, 6.45V breakdown, 10.5V clamping, 143A peak pulse, DO-214AB SMC, -65 to 150°C.","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":"1.5SMC6.8","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Voltage - Breakdown (Min)":"6.45V","Voltage - Clamping (Max) @ Ipp":"10.5V","Voltage - Reverse Standoff (Typ)":"5.8V","Current - Peak Pulse (10/1000µs)":"143A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4447","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC6.8CA-M3%2F9AT/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to this TVS diode?","answer":"The 1.5SMC series uses the standard DO-214AB SMCJ footprint — any unidirectional or bidirectional TVS in the same package with matching standoff and clamping ratings is a candidate.
