The 30.5V clamping ceiling limits the voltage seen by downstream circuitry during a surge. The bidirectional configuration (single channel) means polarity does not matter — it clamps equally on positive and negative transients, simplifying layout on AC-coupled or bipolar signal lines. ## Active production – tape & reel ordering code If you need the same die in a different carrier, confirm the exact ordering code with your distributor.","metaTitle":"1N6114AUS/TR Zener TVS Diode – 500W, 20.9V Breakdown","metaDescription":"Microchip Technology 1N6114AUS/TR Zener TVS diode, 500W peak pulse power, 20.9V min breakdown, 16.7V reverse standoff, bidirectional, SQ-MELF 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":"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)":"20.9V","Voltage - Clamping (Max) @ Ipp":"30.5V","Voltage - Reverse Standoff (Typ)":"16.7V","Current - Peak Pulse (10/1000µs)":"16.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5dbd5050221203b922ebce5a7a6e86e6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can 1N6114AUS/TR replace the through-hole 1N6114A?","answer":"The 1N6114AUS/TR is the surface-mount SQ-MELF version of the 1N6114A. Electrical characteristics (breakdown, standoff, clamping, peak pulse power) are identical, but the package and footprint differ — the SQ-MELF requires a reflow solder profile and a different PCB land pattern than the through-hole part. If your board is designed for the through-hole variant, a direct drop-in replacement is not possible without layout changes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6114AUS-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6114AUS-TR when reusing this data.
