Minimum breakdown voltage is 40.9V, and clamping is held to 59.1V maximum at the peak pulse current of 25.4A. The reverse standoff voltage is 32.7V typical — the device does not conduct below this level, so it sits transparently on a 28V or 32V rail. ## Package and thermal environment Surface-mount SQ-MELF (C) package — the cylindrical body matches the MELF footprint common in high-reliability and military assemblies.","metaTitle":"1N6157AUS Zener TVS Diode – 1500W, 40.9V Breakdown, SQ-MELF","metaDescription":"1N6157AUS from Microchip Technology: bidirectional Zener TVS, 1500W peak pulse power, 40.9V min breakdown, 59.1V clamping, SQ-MELF surface mount.","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","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":"C, SQ-MELF","Voltage - Breakdown (Min)":"40.9V","Voltage - Clamping (Max) @ Ipp":"59.1V","Voltage - Reverse Standoff (Typ)":"32.7V","Current - Peak Pulse (10/1000µs)":"25.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$24.6450","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6157AUS/alternatives.json"},"ai":{"faq":[{"question":"Is 1N6157AUS unidirectional or bidirectional?","answer":"Bidirectional — one channel, clamping symmetrically in both polarities.
