The 6.9 V reverse standoff and 13.4 V clamping voltage at 37.3 A define the protection window for a 5 V or 6 V rail — the TVS triggers before downstream parts see overvoltage, and the clamp holds the transient below the rail's absolute maximum. The single bidirectional channel means one device clamps both polarities, saving board space on AC-coupled or bipolar signal lines where two unidirectional parts would otherwise be needed. ## Hermetic package and 175°C junction rating The SQ-MELF (B, SQ-MELF) package is a hermetic ceramic body — the glass-passivated junction is sealed against moisture and corrosive atmospheres. This makes the 1N6105AUS a natural fit for avionics, downhole, or military-communication boards where conformal coat alone is not enough. The 175°C ceiling gives headroom in high-ambient enclosures or when the TVS is placed near hot power devices; derating the peak pulse power above 25°C follows the standard thermal profile. ## Active production — sourcing via RFQ The SQ-MELF package is not a common commodity footprint, so lead time may differ from plastic SMD TVS parts. Confirm the mating pad geometry and solder profile before committing the layout.","metaTitle":"1N6105AUS TVS Diode – 500W Bidirectional Zener, SQ-MELF","metaDescription":"1N6105AUS from Microchip Technology: 500W peak pulse power, 6.9V standoff, 13.4V clamp, bidirectional Zener TVS in hermetic SQ-MELF.","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, B","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"1N6105","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)":"8.65V","Voltage - Clamping (Max) @ Ipp":"13.4V","Voltage - Reverse Standoff (Typ)":"6.9V","Current - Peak Pulse (10/1000µs)":"37.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.2400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5dbd5050221203b922ebce5a7a6e86e6.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6105AUS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6105AUS when reusing this data.
