No official successor is cited. ## Through-hole axial — DO-201AD footprint The DO-201AD axial package with through-hole mounting suits point-of-use transient clamping on a PCB or terminal strip. The -65°C to 175°C junction temperature range covers military and industrial environments.","metaTitle":"1N6275ARL4 onsemi Mosorb™ Zener TVS - 1500W, Obsolete","metaDescription":"onsemi 1N6275ARL4 Zener TVS diode, Mosorb™ series, 1500 W peak pulse, 12.8 V standoff, DO-201AD axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","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":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6275","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":"$0.6600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1ce676890a04bce4da4e0ab60f37b157.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order 1N6275ARL4 or check stock?","answer":"onsemi lists this part as Obsolete, so new factory orders are not available. We source from our multi-supplier network — submit an RFQ with your target quantity and we will confirm availability and current pricing from distributor inventory or the spot market. The RL4 suffix indicates Tape & Reel packaging; if you need bulk tubes or cut tape, note that on the RFQ."},{"question":"What is the difference between 1N6275A and 1N6275ARL4?","answer":"The base product number is 1N6275. The 'A' suffix typically denotes a tighter tolerance or a specific breakdown voltage bin. The 'RL4' suffix indicates Tape & Reel packaging. The die and electrical ratings (1500 W peak pulse, 12.8 V standoff, 21.2 V clamping) are identical between the two suffixes — the difference is only the packaging format."},{"question":"What is the closest pin-compatible alternative to 1N6275ARL4?","answer":"Within the same onsemi Mosorb™ family, the 1N6275A (same base product number, bulk packaging) is electrically identical. For a second-source alternative, look for a Zener TVS in DO-201AD axial with 12.8 V standoff and 1500 W peak pulse — many manufacturers offer a 1.5KE12 or 1.5KE13A series part that will fit the same footprint and voltage window. Confirm the clamping voltage and breakdown tolerance against your protected rail margin before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/1N6275ARL4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/1N6275ARL4 when reusing this data.
