The 58.9V minimum breakdown voltage sets the protection threshold for a 47.1V reverse standoff rail, meaning this part guards a nominal 48V bus against transients up to 1.5 kW surge energy. ## Package and rework considerations for the C SQ-MELF The C, SQ-MELF package is a surface-mount ceramic barrel with metallized end caps — no leads to bend, no gull-wing to align. It reflows well with a standard solder profile, but the ceramic body has higher thermal mass than a plastic SMD, so the hot-air station needs a few extra seconds at temperature to wet both end caps fully. Pin 1 orientation is marked by a cathode band on the body; the bidirectional version has no polarity mark, so double-check the silkscreen before placing.","metaTitle":"1N6161AUS/TR Zener TVS Diode – 1500W, 58.9V Breakdown","metaDescription":"1N6161AUS/TR Microchip Zener TVS: 1500W peak pulse power, 58.9V min breakdown, bidirectional, C 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":"Tape & Reel (TR)","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)","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)":"58.9V","Voltage - Clamping (Max) @ Ipp":"85.3V","Voltage - Reverse Standoff (Typ)":"47.1V","Current - Peak Pulse (10/1000µs)":"17.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.6401","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6161AUS%2FTR/alternatives.json"},"ai":{"faq":[{"question":"Is 1N6161AUS/TR a bidirectional TVS diode?","answer":"Yes, it has one bidirectional channel, meaning it clamps both positive and negative transients symmetrically."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6161AUS-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6161AUS-TR when reusing this data.
