That power rating, combined with a hermetic SQ-MELF C package, makes it a candidate for high-reliability circuit protection in avionics, defense, and industrial power supplies where transient energy must be clamped without package failure. ## 98.8 V standoff, 178.8 V clamp — the protection window The reverse standoff voltage is 98.8 V typical, meaning the diode draws negligible leakage below that rail. Breakdown starts at 123.5 V minimum, and the clamping voltage peaks at 178.8 V at the rated peak pulse current of 8.4 A. For a 100 V DC bus or a 120 V AC line, this window keeps the protected circuit below destructive overvoltage while avoiding nuisance conduction during normal operation. ## Active production, hermetic package for harsh environments The SQ-MELF C package is a hermetic ceramic surface-mount form factor, suited for high-reliability programs requiring MIL-STD screening. The junction temperature range spans -55°C to 175°C, covering military and downhole thermal extremes. ## Bidirectional single-channel protection With one bidirectional channel, this diode clamps both positive and negative transients symmetrically — useful on AC signal lines, differential data pairs, or ungrounded DC rails where polarity is not fixed. The SQ-MELF footprint is compatible with standard surface-mount assembly processes, though the hermetic body may require reflow profile adjustments compared to plastic packages.","metaTitle":"1N6169AUS Zener TVS Diode – 1500W SQ-MELF, Active Production","metaDescription":"Microchip Technology 1N6169AUS bidirectional Zener TVS, 1500W peak pulse power, 98.8 V standoff, SQ-MELF package, -55°C to 175°C.","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":"1N6169","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)":"123.5V","Voltage - Clamping (Max) @ Ipp":"178.8V","Voltage - Reverse Standoff (Typ)":"98.8V","Current - Peak Pulse (10/1000µs)":"8.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$22.8900","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/1N6169AUS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6169AUS when reusing this data.
