The DO-201 footprint is standard across the 1.5KE series, so a single board layout serves the full voltage range if the BOM needs to swap protection levels.","metaTitle":"Littelfuse 1.5KE150 TVS Diode, 1500W, 128V Standoff, DO-201","metaDescription":"Littelfuse 1.5KE150 Zener TVS diode, 1500W peak pulse power, 128V reverse standoff, 217.35V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5KE","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"135.45V","Voltage - Clamping (Max) @ Ipp":"217.35V","Voltage - Reverse Standoff (Typ)":"128V","Current - Peak Pulse (10/1000µs)":"7.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6835","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE150/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the 1.5KE150 and how is it quoted?","answer":"Submit an RFQ for current availability and pricing — no standing stock is held, and lead time is confirmed at quote time."},{"question":"What is the 1.5KE150's type and series?","answer":"It is a Zener-type TVS diode from the Littelfuse 1.5KE series."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5KE150","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5KE150 when reusing this data.
