It handles 1500W peak pulse power (1.5kW) in a DO-201AD axial package — the same footprint as the classic 1.5KE series, so it drops into existing board layouts without a pad revision. Breakdown occurs at 40.9V minimum, clamping at 59.3V at the rated peak pulse current. That 18.5V window between standoff and clamp gives enough margin to keep a 36V bus from seeing damaging overvoltage during a surge, but the clamping voltage is high enough that downstream 40V-rated parts still need their own derating check. ## Sourcing an obsolete part — what to expect onsemi lists the 1N6286ARL4G as Obsolete. Sourcing relies on independent inventory — we can search our network of franchised and non-franchised suppliers for remaining stock. The part ships in Tape & Reel (TR) format, which is typical for automated insertion of axial diodes. If your line uses bulk or cut-tape, the reel can be broken — just specify the quantity and preferred packaging in the RFQ. ## Temperature range and mounting Junction temperature range spans -65°C to 175°C (TJ) — wide enough for industrial and outdoor telecom enclosures where the ambient inside the cabinet can hit 85°C and the diode self-heats during a surge. The through-hole DO-201AD axial body conducts heat through the leads into the PCB copper; keep the lead length short to minimise thermal resistance. No power line protection — this part is intended for signal or low-power DC rail clamping, not AC mains. If your application requires line-side transient suppression, look at a metal-oxide varistor or a higher-energy TVS rated for AC coupling.","metaTitle":"1N6286ARL4G Zener TVS Diode – 1500W, 36.8V Standoff","metaDescription":"onsemi Mosorb™ 1N6286ARL4G Zener TVS diode, 1500W peak pulse power, 36.8V reverse standoff, 40.9V breakdown, unidirectional, 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":"1N6286","Operating Temperature":"-65°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"40.9V","Voltage - Clamping (Max) @ Ipp":"59.3V","Voltage - Reverse Standoff (Typ)":"36.8V","Current - Peak Pulse (10/1000µs)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/717ad1fc0ab391931f54c66e75e89e87.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1N6286ARL4G unidirectional or bidirectional?","answer":"It is a unidirectional Zener TVS — one channel, cathode band on the body.
