The 1.5SMC440CA is a bidirectional Zener-type TVS diode from Littelfuse's 1.5SMC series, designed to clamp transient overvoltages on a 376 V nominal rail. ## Key ratings and what they mean for the BOM The 376 V reverse standoff voltage (Vrwm) defines the maximum continuous DC or peak AC voltage the diode blocks without conducting — your rail must stay below this under steady-state conditions. The 418 V minimum breakdown voltage (Vbr) is where clamping starts; a 602 V maximum clamping voltage (Vc) at 2.5 A peak pulse current (Ipp) limits the transient spike seen by downstream components. Single bidirectional channel means one device protects a pair of rails or a single line referenced to ground, saving board space versus two unidirectional diodes in anti-series. The supplier device package is listed as DO-214AB (SMCJ), confirming interchangeability with JEDEC SMCJ footprints on existing PCB layouts.","metaTitle":"Littelfuse 1.5SMC440CA TVS Diode, 1500W, 376V, DO-214AB","metaDescription":"Littelfuse 1.5SMC440CA bidirectional TVS diode, 1500W peak pulse power, 376V reverse standoff, 602V clamping, DO-214AB SMC package.","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)":"418V","Voltage - Clamping (Max) @ Ipp":"602V","Voltage - Reverse Standoff (Typ)":"376V","Current - Peak Pulse (10/1000µs)":"2.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4a8a4359c4139865ec4feb6a6da8698b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC440CA/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5SMC440CA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5SMC440CA when reusing this data.
