Under a 10/1000µs surge waveform it clamps at 45.7V maximum while conducting 33A peak pulse current, and the device is rated to absorb 1500W of peak pulse power. The DO-13 through-hole package is a metal-can hermetic style that handles the thermal pulse of a 1.5kW event without cracking the die attach. ## Junction temperature range and mounting This makes the 1N6051A/TR suitable for under-hood automotive, avionics, or downhole instrumentation where ambient temperatures push junction temperatures above 150°C.","metaTitle":"1N6051A/TR TVS Diode – 28V Standoff, 1500W, DO-13, Microchip","metaDescription":"1N6051A/TR bidirectional Zener TVS diode from Microchip Technology. 28V reverse standoff, 45.7V clamp, 1500W peak pulse power, DO-13 through-hole package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-13","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-13","Voltage - Breakdown (Min)":"31.4V","Voltage - Clamping (Max) @ Ipp":"45.7V","Voltage - Reverse Standoff (Typ)":"28V","Current - Peak Pulse (10/1000µs)":"33A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$22.9650","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8e9aa18e7137d2d8b32c3a99aef403c3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6051A%2FTR/alternatives.json"},"ai":{"faq":[{"question":"Can 1N6051A/TR be used for 24V circuit protection?","answer":"Yes. The reverse standoff voltage is 28V, which is 4V above a nominal 24V rail. That gives enough margin to avoid false triggering during normal operation while still clamping before the rail sees damaging overvoltage."},{"question":"Is 1N6051A/TR bidirectional?","answer":"Yes, it has one bidirectional channel. It clamps both positive and negative transients with a single device, so you do not need to worry about polarity when placing it on the board."},{"question":"What package does 1N6051A/TR come in?","answer":"It is supplied in a DO-13 through-hole package, with the TR suffix indicating Tape & Reel packaging for automated handling."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6051A-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6051A-TR when reusing this data.
