The DO-201AA axial-lead package (DO-27 equivalent) is a through-hole part. ## Obsolete — sourcing through independent channels Littelfuse lists the 1.5KE180C as obsolete. No official successor order code is recorded in the lifecycle data. If you are qualifying a replacement, the closest functional match in the same 1.5KE family would share the same DO-201 package and 1500W rating but with a standoff voltage that matches your rail.","metaTitle":"1.5KE180C Littelfuse TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Obsolete 1.5KE180C Zener TVS diode from Littelfuse. 1500W peak pulse, 154V standoff, 258.3V 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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"162V","Voltage - Clamping (Max) @ Ipp":"258.3V","Voltage - Reverse Standoff (Typ)":"154V","Current - Peak Pulse (10/1000µs)":"6.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7081","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE180C/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5KE180C","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5KE180C when reusing this data.
