No power line protection rating — the device is intended for general-purpose transient suppression on signal, data, or low-voltage DC rails where the standoff voltage matches the nominal rail. ## Sourcing reality — obsolete, available through independent channels Availability and pricing are quoted per lot against the BOM quantity — no stock-holding claim, no deferred manufacturer channel. The base product number 1.5KE51 covers the family; the -T suffix indicates Tape & Reel packaging. Parts on cut tape or full reels are both available through the spot market depending on the lot.","metaTitle":"1.5KE51A-T Diodes Zener TVS, 1500W, DO-201, Obsolete","metaDescription":"1.5KE51A-T from Diodes Inc: Zener TVS diode, 1500W peak pulse, 43.6V standoff, DO-201 axial.","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":"1.5KE51","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"48.5V","Voltage - Clamping (Max) @ Ipp":"70.1V","Voltage - Reverse Standoff (Typ)":"43.6V","Current - Peak Pulse (10/1000µs)":"21.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b6b9d4121cb66208511919f4a66769e1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order 1.5KE51A-T or check current availability?","answer":"The 1.5KE51A-T is obsolete from Diodes Incorporated and sourced through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/1.5KE51A-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/1.5KE51A-T when reusing this data.
