Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE350C-B is a through-hole device suited for point-of-entry surge suppression on terminal blocks or PCB-mount with lead forming. The DO-201 footprint is standard across the 1.5KE family, so a single board layout accepts the full voltage range from 6.8 V to 440 V. Littelfuse has marked the 1.5KE350C-B as obsolete. The 1.5KE series remains a widely used TVS platform, and the DO-201 package is common across multiple manufacturers. A cross-reference search against the 300 V standoff and bidirectional polarity may yield a functional equivalent, but no pin-compatible drop-in is documented here.","metaTitle":"Littelfuse 1.5KE350C-B TVS Diode, 1500W, Bidirectional","metaDescription":"Obsolete Littelfuse 1.5KE350C-B bidirectional TVS diode, 1500W peak pulse power, 300V standoff, DO-201 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5KE","Package":"Bulk","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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"315V","Voltage - Clamping (Max) @ Ipp":"506.1V","Voltage - Reverse Standoff (Typ)":"300V","Current - Peak Pulse (10/1000µs)":"3.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the 1.5KE350C-B use?","answer":"It comes in a DO-201AA (DO-27) axial-lead through-hole package, supplied in bulk."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5KE350C-B","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5KE350C-B when reusing this data.
