The \"CA\" suffix marks the bidirectional variant, meaning it clamps both polarities on a single channel — the right fit for AC signal lines, differential pairs, or any node that swings above and below ground. ## Three TVS voltage specs — which one drives the design 58.1 V reverse standoff (typ) is the voltage you can apply continuously without the device conducting — the normal operating window for the protected rail. Breakdown starts at 64.6 V minimum, which is where the TVS begins to avalanche and absorb surge current. With 16.3 A peak pulse current at the clamping voltage, the 1.5 kW rating is sized for the IEEE 61000-4-5 waveform class typically seen at the board-level port on industrial and telecom equipment — not for primary power-line entry where 10 kA+ survivability is required. Classifying it as general-purpose protection rather than power-line protection means it belongs on signal and low-power rail protection, not on the AC mains side. ## Junction temperature and board-fit notes The DO-214AB package mounts to the standard SMC pad footprint; the supplier device package designation DO-214AB (SMCJ) confirms the industry-standard land pattern for reflow or hand assembly. Tape-and-reel packaging suits high-volume SMT line placement.","metaTitle":"Vishay 1.5SMC68CA-M3/57T TVS Diode, 1.5 kW, 92V Clamping","metaDescription":"Vishay 1.5SMC68CA-M3/57T bidirectional TVS Zener, 1500 W peak pulse, 92 V clamping, 58.1 V standoff.","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":"1.5SMC68","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)":"64.6V","Voltage - Clamping (Max) @ Ipp":"92V","Voltage - Reverse Standoff (Typ)":"58.1V","Current - Peak Pulse (10/1000µs)":"16.3A"}},"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/1.5SMC68CA-M3%2F57T/alternatives.json"},"ai":{"faq":[{"question":"How can I source the 1.5SMC68CA-M3/57T and get a quote?","answer":"The part ships tape-and-reel per the standard package listing."},{"question":"What is the 1.5SMC68CA-M3/57T's listed device type?","answer":"The device is a Zener-based bidirectional TVS (transient voltage suppressor) — the CA suffix in the order code confirms the bidirectional polarity configuration on a single channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC68CA-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/1.5SMC68CA-M3-57T when reusing this data.
