This means the manufacturer has ceased production with no last-time-buy window remaining — the only available units are existing stock held by independent distributors. Unidirectional Zener TVS with a 408 V reverse standoff voltage and a minimum breakdown of 432 V — this sets the clamping threshold. The device starts conducting at the breakdown edge, protecting downstream circuitry from transients that exceed the normal rail voltage. Supplied in DO-214AB (SMC) package, also designated SMCJ by some suppliers. The surface-mount footprint is shared across the 1.5SMC series — a single PCB pad layout serves the full voltage range from 5.0 V to 480 V standoff. Tape-and-reel packaging supports automated pick-and-place assembly. The 1500 W peak pulse capability in a DO-214AB body means the die-to-pad thermal path is sized for the surge energy — board copper area under the cathode tab affects the derating at elevated ambient temperatures.","metaTitle":"Littelfuse 1.5SMC480 TVS, 432V Breakdown, DO-214AB","metaDescription":"Obsolete Littelfuse 1.5SMC480 Zener TVS diode, 1500W peak pulse, 408V standoff, DO-214AB SMC package.","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)","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":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"432V","Voltage - Clamping (Max) @ Ipp":"690.9V","Voltage - Reverse Standoff (Typ)":"408V","Current - Peak Pulse (10/1000µs)":"2.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0970","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/118f1b70ec0f0941665a20e5472af60a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC480/alternatives.json"},"ai":{"faq":[{"question":"How do I check stock and pricing for the 1.5SMC480?","answer":"Submit an RFQ — the sourcing desk verifies date-code, quantity, and lot traceability before quoting."},{"question":"What is the 1.5SMC480's breakdown and clamping voltage?","answer":"Minimum breakdown is 432 V; maximum clamping at peak pulse current is 690.9 V.
