Peak pulse power is rated 1500 W (1.5 kW), and the junction temperature ceiling is 175 °C — the wide temperature band covers outdoor enclosures and industrial bay ambient without derating in most panel configurations, though the board-level thermal path still sets the actual surge-withstand margin. ## Last-buy reality and sourcing posture Available through independent distribution as surplus or excess inventory — lot traceability and shelf age should be confirmed at RFQ since Zener characteristics can drift with long storage, and the lead solderability on aged axial parts warrants inspection on receipt.","metaTitle":"1N6269A-E3/51, 12.1V Clamping Zener, 1500W Peak Pulse","metaDescription":"Vishay 1N6269A-E3/51 Zener (TransZorb®), 7.02V standoff, 12.1V clamping at 124A, 1.5 kW peak pulse, DO-201AA axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Last Time Buy","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6269","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"7.79V","Voltage - Clamping (Max) @ Ipp":"12.1V","Voltage - Reverse Standoff (Typ)":"7.02V","Current - Peak Pulse (10/1000µs)":"124A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6269A-E3%2F51/alternatives.json"},"ai":{"faq":[{"question":"What is the 1N6269A-/51 used for?","answer":"This is a unidirectional Zener (TransZorb®) transient voltage suppressor — it clamps overvoltage transients on a single power rail, protecting downstream ICs and circuitry from surge events up to 124 A peak pulse in the 10/1000 µs waveform window."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1N6269A-E3-51","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1N6269A-E3-51 when reusing this data.
