The junction temperature range spans -55°C to 175°C, which puts this part into military/aerospace and downhole equipment where the ambient can exceed 125°C and the self-heating from repetitive pulses must stay within the die's thermal budget. ## Clamping voltage and pulse current Breakdown voltage minimum is 7.79V; the clamping voltage at peak pulse current is 12.1V max — this 4.3V window between standoff and clamp tells the designer how much overvoltage the downstream circuitry must survive before the Zener conducts fully. ## Surface-mount MELF for harsh environments Packaged in SQ-MELF, C — a cylindrical surface-mount body with metallized end caps. The MELF footprint is less common than a SOD or SMB, so confirm the solder pad geometry matches the IPC-7351 standard for this package before committing the PCB layout. The base product number 1N6140 covers a family of voltage variants; the AUS suffix specifies the bidirectional polarity and the SQ-MELF package.","metaTitle":"1N6140AUS Zener TVS Diode – 1500W, SQ-MELF, Microchip","metaDescription":"1N6140AUS Zener TVS diode from Microchip Technology. 1500W peak pulse power, 6.2V reverse standoff, bidirectional, SQ-MELF C 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":"Bulk","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"SQ-MELF, C","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6140","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"C, SQ-MELF","Voltage - Breakdown (Min)":"7.79V","Voltage - Clamping (Max) @ Ipp":"12.1V","Voltage - Reverse Standoff (Typ)":"6.2V","Current - Peak Pulse (10/1000µs)":"124A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$24.0750","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6140AUS/alternatives.json"},"ai":{"faq":[{"question":"Is 1N6140AUS bidirectional?","answer":"Yes — it has one bidirectional channel, meaning it clamps both positive and negative transients symmetrically.
