The SQ-MELF B package suits surface-mount assembly on boards where a hermetically sealed glass body is preferred over plastic for moisture resistance or high-reliability programs. ## Junction temperature range and operating environment The junction temperature range spans -55°C to 175°C, which covers military, avionics, and downhole applications where the ambient temperature can exceed the ceiling of many plastic-packaged TVS diodes. The wide temperature window also means the leakage current and clamping voltage shift less across the operating band than a narrower-grade part — a real advantage when the protected rail must stay within a tight voltage window at high temperature. ## Active production — no obsolescence concern for new builds Microchip lists the 1N6117AUS/TR as Active, so it remains available for both new-design-in and ongoing BOM replenishment. ## Bidirectional channel — one device protects both polarities With a single bidirectional channel, this TVS clamps transients of either polarity symmetrically, which simplifies board layout on AC signal lines or dual-polarity DC rails where two unidirectional devices would otherwise be needed. The 28.5V minimum breakdown voltage ensures the device does not conduct during normal 22.8V standoff operation, leaving the signal rail undisturbed until a surge event occurs.","metaTitle":"1N6117AUS/TR – Microchip Zener TVS, 500W, Bidirectional","metaDescription":"1N6117AUS/TR from Microchip Technology: Zener TVS diode, 500W peak pulse power, bidirectional, 22.8V standoff, 41.6V clamp.","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, B","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"B, SQ-MELF","Voltage - Breakdown (Min)":"28.5V","Voltage - Clamping (Max) @ Ipp":"41.6V","Voltage - Reverse Standoff (Typ)":"22.8V","Current - Peak Pulse (10/1000µs)":"12A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.4350","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5dbd5050221203b922ebce5a7a6e86e6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between 1N6117AUS and 1N6117AUS/TR?","answer":"The /TR suffix indicates Tape & Reel packaging. The bare 1N6117AUS (without /TR) is typically supplied in bulk or tube. The electrical specifications — 500W peak pulse power, 22.8V standoff, 41.6V clamp — are identical between the two suffixes.
