This part is available through independent surplus and excess-inventory channels. Sourcing is lot-specific — date-code spread and packaging condition (sealed reels vs cut tape) are confirmed at RFQ. ## Temperature grade and mounting Rated for continuous junction temperatures from -55°C to 175°C, the device suits high-ambient environments such as outdoor telecom cabinets or under-hood automotive modules where the TVS must survive under bias near the thermal limit. Through-hole DO-201AA (DO-27) axial package — the leads are tin-plated copper, compatible with wave-solder assembly. The body length and lead diameter match standard 1.5KE series footprints; no board layout change from other 1.5KE parts.","metaTitle":"1.5KE27A-T Diodes Inc Zener TVS, 1500W, DO-201","metaDescription":"Obsolete 1.5KE27A-T Zener TVS diode, 1500W peak pulse, 23.1V standoff, 40A Ipp. Sourced to order against RFQ through independent distribution.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diodes Incorporated","Type":"Zener","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"1.5KE27","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"25.7V","Voltage - Clamping (Max) @ Ipp":"37.5V","Voltage - Reverse Standoff (Typ)":"23.1V","Current - Peak Pulse (10/1000µs)":"40A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b6b9d4121cb66208511919f4a66769e1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the 1.5KE27A-T or check stock?","answer":"Submit an RFQ for the 1.5KE27A-T."},{"question":"What is the closest pin-compatible alternative to the 1.5KE27A-T?","answer":"A parametric match from the same 1.5KE series (same DO-201AA footprint, same 1500 W rating) may serve as a functional replacement, but the exact breakdown voltage and standoff must be verified against the circuit's protection threshold."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/1.5KE27A-T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diodes-inc/1.5KE27A-T when reusing this data.
