The 21.2 V clamping ceiling at peak pulse current is the figure to use when estimating let-through voltage into the protected load. -65°C to 175°C junction temperature range is unusually wide for a leaded TVS — this puts it in the running for engine-adjacent or industrial equipment that sees high ambient swings, not just benign indoor environments. ## DO-201AD axial — board integration realities Through-hole DO-201AD package means the leads go through plated holes and get wave-soldered or hand-soldered — the axial body sits flat against the board, and thermal cycling fatigue at the lead bend is the main failure mode to watch in high-cycling applications. Tape-and-reel packaging means automated axial insertion is the natural assembly path; loose leads in a cut-tape or bulk bag are not the standard pack form for this PN. Surplus and independent distribution channels are the sourcing path for this PN — quantities are lot-specific and availability is confirmed at RFQ. Date-code spread on sealed factory reels matters here: a single consistent date-code reel from one production run carries far more reliability than a mixed-date lot that may have seen reflow or extended shelf time without dry storage.","metaTitle":"Littelfuse 1N6275ARL4G Zener TVS, 1500W Peak, DO-201AD","metaDescription":"Littelfuse 1N6275ARL4G Mosorb™ Zener TVS diode, 12.8V standoff / 14.3V breakdown, 1500W peak pulse, DO-201AD axial, obsolete — quoted to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"Mosorb™","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AD, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6275A","Operating Temperature":"-65°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"14.3V","Voltage - Clamping (Max) @ Ipp":"21.2V","Voltage - Reverse Standoff (Typ)":"12.8V","Current - Peak Pulse (10/1000µs)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b2bad05ac2a782d44789dbfb00c46ecc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6275ARL4G/alternatives.json"},"ai":{"faq":[{"question":"Where can I source the 1N6275ARL4G and what are the lead time and price?","answer":"Sealed factory-reel stock with consistent date-code is the preference for reliability-sensitive applications; mixed-lot or repackaged stock carries higher counterfeit risk and should be verified before assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1N6275ARL4G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1N6275ARL4G when reusing this data.
