Availability and pricing are confirmed at RFQ time against the required quantity. ## 44.7V breakdown, 64.8V clamp — a 40V rail protector The 1N6287A is a unidirectional Zener TVS diode from the Mosorb™ series, rated for 1500 W peak pulse power. The reverse standoff voltage is 40.2 V, breakdown minimum is 44.7 V, and clamping at peak pulse current is 64.8 V. The axial package (through-hole) supports board-level replacement and rework without special profile equipment. Operating temperature spans -65°C to 175°C, suiting extreme environments. ## Peak pulse power and clamping margin The 1500 W peak pulse rating defines the surge energy the diode can absorb. The 64.8 V clamp sets the voltage seen by downstream circuitry during an event. No power line protection feature is listed — this is a general-purpose transient suppressor, not a dedicated rail comb clamp.","metaTitle":"1N6287A onsemi Mosorb™ Zener TVS – Obsolete, 1500W, DO-201AD","metaDescription":"1N6287A is obsolete. onsemi Mosorb™ Zener TVS, 1500W peak pulse, 44.7V breakdown, 64.8V clamp, 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":"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":"1N6287","Operating Temperature":"-65°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"44.7V","Voltage - Clamping (Max) @ Ipp":"64.8V","Voltage - Reverse Standoff (Typ)":"40.2V","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can I order 1N6287A or check stock?","answer":"1N6287A is obsolete — onsemi no longer manufactures it.
