That 92V clamp ceiling is the figure that defines what the downstream circuitry survives. ## Packaging and reel availability Supplied in Tape & Reel (TR) for automated placement and Cut Tape (CT) for low-volume or prototype runs. ## General-purpose designation and what it means That is the correct read for non-safety-critical boards: consumer, industrial control, power supplies, and telecom infrastructure where the transient protection function is functional, not regulated. If you need automotive or defence screening, look at the AEC-Q101-screened siblings in the same 1.5SMC package.","metaTitle":"Littelfuse 1.5SMC68CA TVS Diode, 58.1V Standoff, 92V Clamp","metaDescription":"Littelfuse 1.5SMC68CA bidirectional TVS diode, 58.1V standoff, 64.6V breakdown, 92V clamp, 1500W peak pulse, DO-214AB SMC package, -55 to 150°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5SMC","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":"1.5SMC","Operating Temperature":"-55°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)":"16.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/118f1b70ec0f0941665a20e5472af60a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC68CA/alternatives.json"},"ai":{"faq":[{"question":"What voltage does the 1.5SMC68CA actually clamp at?","answer":"The maximum clamping voltage at the rated peak pulse current (16.5 A, 10/1000 µs) is 92 V.
