The 86.6V reverse standoff leaves headroom for a nominal 72V rail with 20% tolerance, so the diode stays off during normal operation and only conducts during a surge. ## Active production — no LTB pressure Microchip lists the 1N6167AUS as Active. The SQ-MELF package is a standard surface-mount hermetic package — store the reels dry, but the ceramic body handles soldering reflow without moisture sensitivity level concerns typical of plastic packages. Rated for -55°C to 175°C junction temperature, this part suits outdoor telecom cabinets, avionics, and downhole instrumentation where ambient heat or cold-soak extremes are routine. The 1500W peak pulse rating is derated linearly above 25°C — at 175°C the derating factor drops to zero, so keep the average junction temperature below 150°C in repetitive surge applications.","metaTitle":"1N6167AUS Zener TVS Diode – 1500W, 104.5V Breakdown, SQ-MELF","metaDescription":"1N6167AUS from Microchip Technology: Zener TVS diode, 1500W peak pulse power, 104.5V min breakdown, 151.3V 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)":"104.5V","Voltage - Clamping (Max) @ Ipp":"151.3V","Voltage - Reverse Standoff (Typ)":"86.6V","Current - Peak Pulse (10/1000µs)":"9.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.microsemi.com/document-portal/doc_download/127854-1n6138us-1n6173aus-tvs-diode-series-datasheet","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6167AUS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6167AUS when reusing this data.
