This 37.5V clamp ceiling is the figure a downstream IC's absolute-maximum input voltage must stay above — if the protected rail sees a surge, the TVS holds it under that limit. ## No power line protection — signal and DC bus only Being a unidirectional device, it clamps only one polarity — the cathode is tied to the protected rail, and the anode to ground. For AC or bidirectional lines, two devices back-to-back or a bidirectional TVS would be needed.","metaTitle":"1.5SMC27AT3G Littelfuse TVS, 1500W, 23.1V Standoff, DO-214AB","metaDescription":"Littelfuse 1.5SMC27AT3G Zener TVS, 1500W peak pulse, 23.1V reverse standoff, 37.5V clamping.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMC","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"25.7V","Voltage - Clamping (Max) @ Ipp":"37.5V","Voltage - Reverse Standoff (Typ)":"23.1V","Current - Peak Pulse (10/1000µs)":"40A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ea97bb520e37528ab309c554c0bb147d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC27AT3G/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5SMC27AT3G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5SMC27AT3G when reusing this data.
