Its 500 W peak pulse power rating gives you a defined energy budget for surge protection on DC buses, relay coils, or industrial sensor supplies. The reverse standoff voltage of 47.1 V is the maximum continuous voltage the protected line can carry without the diode conducting — set your operating rail below this with margin. Clamping starts at 58.9 V minimum breakdown and limits the surge to 85.3 V at 5.9 A peak pulse current. ## Junction rating from -55 to 175°C The junction temperature range spans -55°C to 175°C — full military-grade thermal capability. That matters for outdoor telecom cabinets, engine-bay electronics, or any environment where the ambient cycles beyond commercial limits. The axial through-hole package handles the heat dissipation better than a small SMD package would at this power level. No power line protection feature — this is a basic TVS without internal filtering or coordinated crowbar; the clamping action is the only protection mechanism. Bidirectional single-channel suits AC-coupled lines or bipolar supplies. ## Active production — sourcing through distribution The base product number is 1N6125; the 'A' suffix indicates a tighter breakdown tolerance variant. Through-hole axial package in bulk — no reel or tape option, so plan for manual or tube-fed insertion. Quoted to order against your BOM quantity. For volume or blanket orders, we can source across our distribution network.","metaTitle":"1N6125A Zener TVS Diode – 47.1 V Standoff, 500 W, Axial","metaDescription":"1N6125A bidirectional Zener TVS diode from Microchip Technology. 47.1 V reverse standoff, 58.9 V min breakdown, 85.3 V clamping at 5.9 A. 500 W peak pulse","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"B, Axial","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"1N6125","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Voltage - Breakdown (Min)":"58.9V","Voltage - Clamping (Max) @ Ipp":"85.3V","Voltage - Reverse Standoff (Typ)":"47.1V","Current - Peak Pulse (10/1000µs)":"5.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.4400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c72f565c96d1fb1ddee384734173c93c.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6125A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6125A when reusing this data.
