The DO-201 footprint is a standard axial-lead diode layout — the 0.052-inch lead diameter fits a 0.040-inch plated through-hole, and the body length of about 9.5 mm requires clearance on the board edge or in a lead-bending fixture for vertical or horizontal placement. The single bidirectional channel means the part clamps both polarities with one device, simplifying PCB layout for AC-coupled or floating signal lines. ## Obsolete lifecycle and sourcing posture Littelfuse has marked the 1.5KE10C-B as obsolete. No pin-compatible direct replacement from Littelfuse is documented, so a board-level change would be needed to migrate to a current-production TVS diode.","metaTitle":"Littelfuse 1.5KE10C-B TVS Diode, 1500W, DO-201","metaDescription":"Obsolete Littelfuse 1.5KE10C-B bidirectional Zener TVS diode, 1500W peak pulse, 8.55V standoff, 15.23V clamping, DO-201AA axial.","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)":"9V","Voltage - Clamping (Max) @ Ipp":"15.23V","Voltage - Reverse Standoff (Typ)":"8.55V","Current - Peak Pulse (10/1000µs)":"104.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/149eca2cbf10498ecc0c7eab912fe9f4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the 1.5KE10C-B use?","answer":"It uses a DO-201AA axial package (also known as DO-27), a standard through-hole footprint for power TVS diodes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5KE10C-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/1.5KE10C-B when reusing this data.
