Through-hole DO-201AA (DO-27) axial package, supplier device package DO-201. The axial leads suit point-to-point wiring or PCB through-hole mounting with 0.040-inch diameter leads — standard for this power class. The 1.5KE series is a mature, widely stocked line — cross-reference to other 1500W bidirectional TVS in DO-201 is possible but requires verifying the standoff and clamping voltages match your protection threshold.","metaTitle":"Littelfuse 1.5KE300CA TVS Diode, 1500W, 256V Standoff","metaDescription":"Littelfuse 1.5KE300CA bidirectional Zener TVS diode, 1500W peak pulse power, 256V reverse standoff, 414V clamping at 3.7A.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5KE","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"285V","Voltage - Clamping (Max) @ Ipp":"414V","Voltage - Reverse Standoff (Typ)":"256V","Current - Peak Pulse (10/1000µs)":"3.7A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE300CA/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for 1.5KE300CA?","answer":"Submit an RFQ against your BOM quantity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5KE300CA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5KE300CA when reusing this data.
