Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE180ARL is a through-hole device intended for hand insertion or wave solder. The axial leads suit point-to-point wiring on terminal strips or PCB mounting with lead forming. No MSL rating is listed, but axial devices of this class are typically moisture-insensitive — no bake required before assembly if stored in a dry environment.","metaTitle":"STMicroelectronics 1.5KE180ARL TVS, 1500W, 154V Standoff","metaDescription":"1.5KE180ARL is a 1500W unidirectional TVS diode from STMicroelectronics, 154V standoff, 317V clamping.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"1.5KE, TRANSIL™","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-","Power Line Protection":"No","Capacitance @ Frequency":"725pF @ 1MHz","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"171V","Voltage - Clamping (Max) @ Ipp":"317V","Voltage - Reverse Standoff (Typ)":"154V","Current - Peak Pulse (10/1000µs)":"31.5A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3584","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/089e26c8bbf5e28593f663899fc6cea1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE180ARL/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for 1.5KE180ARL?","answer":"For a functional equivalent, consider a 1500W unidirectional TVS with a 154V standoff voltage in a DO-201 package from the same TRANSIL™ family or a cross from another manufacturer — verify breakdown and clamping voltages against your circuit's protection requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/1.5KE180ARL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/1.5KE180ARL when reusing this data.
