At a 14.6 A surge current the clamp sits at 104 V, which means the protected node sees a maximum of 104 V regardless of how high the incoming transient tries to push it — the downstream IC sees that ceiling, not the raw surge amplitude. ## Package and what it asks of the board The DO-214AB (SMC) is a standard surface-mount outline — the cathode tab is the primary thermal path, so the pad footprint and solder joint geometry directly set the junction-to-ambient thermal resistance; thermal relief on the pad matters more than the part itself for long-term reliability under repeated transients. Reel packaging signals the part is reeled for high-speed pick-and-place — confirm the reel pitch and leader length match the mounter's feeder specification before committing to the panel layout. ## Where the temperature and qualification grade put this part Power line protection is listed as No — this part is not UL 497B listed for dedicated telecom loop circuits; it serves as a general board-level transient suppressor on data, control, or power rails that do not require that certification. ## Active status and sourcing posture The standard SMC footprint means pin-compatible cross-parts exist across the TVS diode market if a second-source hedge is needed for the BOM position.","metaTitle":"Vishay 1.5SMC75CA-E3/57T, 104V TVS Diode, DO-214AB","metaDescription":"Vishay Zener TVS diode, DO-214AB, 104V clamp, 1.5kW peak, -65°C to 150°C, Active","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) Cut Tape (CT)","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":"1.5SMC75","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)":"71.3V","Voltage - Clamping (Max) @ Ipp":"104V","Voltage - Reverse Standoff (Typ)":"64.1V","Current - Peak Pulse (10/1000µs)":"14.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC75CA-E3%2F57T/alternatives.json"},"ai":{"faq":[{"question":"What type is the 1.5SMC75CA-/57T — is it a Zener or a TVS diode?","answer":"It is classified as a Zener type in the spec record, specifically a bidirectional transient voltage suppressor using the Vishay TransZorb® design — the clamping and peak pulse ratings are what drive the selection for overvoltage protection on a board rail."},{"question":"What series does the 1.5SMC75CA-/57T belong to?","answer":"The part is in the 1.5SMC series, Vishay's TransZorb® family — a 1.5 kW peak pulse power class that sits in the DO-214AB SMC footprint and covers a range of standoff voltages in the same mechanical form factor."},{"question":"What compliance documentation is available for 1.5SMC75CA-/57T?","answer":"The spec record does not list specific certifications (RoHS, REACH, UL, IEC) on this listing — confirm the material composition and environmental compliance status against the Vishay datasheet and RoHS declaration before specifying into regulated end products."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC75CA-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/1.5SMC75CA-E3-57T when reusing this data.
