The SQ-MELF package is a hermetic ceramic barrel with metallised end caps — no plastic mould compound to absorb moisture, no popcorn risk during reflow. The C suffix indicates the standard outline per JEDEC DO-213AB. Microchip Technology lists the 1N6161AUS as Active. The base product number 1N6161 covers a family of voltage grades in the same hermetic SQ-MELF footprint. If your design needs a different standoff voltage, the 1N6161 family shares the same package and power rating.","metaTitle":"1N6161AUS Zener TVS Diode – 1500W Peak Pulse, SQ-MELF","metaDescription":"1N6161AUS from Microchip Technology: Zener TVS diode, 1500W peak pulse power, bidirectional, 47.1V standoff, 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","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6161","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":"$21.6000","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6161AUS/alternatives.json"},"ai":{"faq":[{"question":"Is the 1N6161AUS a bidirectional or unidirectional device?","answer":"Bidirectional — a single channel clamps both positive and negative transients symmetrically, with the same breakdown and clamping voltages in both directions."},{"question":"What is the closest pin-compatible alternative to the 1N6161AUS in the same family?","answer":"The 1N6161 family uses the same SQ-MELF C package and 1500 W power rating.
