It clamps at 14.5 V maximum with a reverse standoff of 8.55 V, protecting downstream circuitry from voltage transients in general-purpose applications. Housed in a DO-201AD axial leaded package, it mounts through-hole — the same footprint as the industry-standard 1.5KE series, making it a drop-in replacement for many 1500 W axial TVS parts in legacy designs. ## Sourcing this obsolete part — what to expect onsemi lists the 1N6271A as Obsolete. No official successor is recorded in the available documentation, so the BOM line needs a cross-reference or a last-time-buy strategy if stock is still needed for production or repair. ## Package and temperature range for repair fit The DO-201AD axial package is the same body size as the 1.5KE series — 9.1 mm body length, 1.3 mm lead diameter — so it fits existing through-hole pads on boards designed for that footprint. Operating temperature spans -65°C to 175°C junction, covering industrial and automotive under-hood environments.","metaTitle":"1N6271A onsemi Mosorb™ Zener TVS – 1500 W, DO-201AD Axial","metaDescription":"1N6271A onsemi Mosorb™ Zener TVS diode, 1500 W peak pulse power, 8.55 V reverse standoff, DO-201AD axial package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","Type":"Zener","Series":"Mosorb™","Package":"Bulk","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":"1N6271","Operating Temperature":"-65°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"9.5V","Voltage - Clamping (Max) @ Ipp":"14.5V","Voltage - Reverse Standoff (Typ)":"8.55V","Current - Peak Pulse (10/1000µs)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1ce676890a04bce4da4e0ab60f37b157.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the 1N6271A or check availability?","answer":"The 1N6271A is obsolete per onsemi.
