The 18.2 V standoff sits low enough to avoid nuisance clamping during normal ripple, yet the 21.66 V minimum breakdown triggers early enough to protect downstream regulators and logic. ## SQ-MELF package – footprint and thermal handling Housed in an SQ-MELF B package (surface-mount, cylindrical body with wraparound metalized ends), the 1N6115US is designed for automated pick-and-place assembly. The metalized end caps provide a direct thermal path to the board copper, which is critical for dissipating the pulse heat. The package is rated for the full -55°C to 175°C junction temperature range, so it suits high-temperature environments like engine bays or avionics compartments.","metaTitle":"1N6115US Zener TVS Diode – 500W Bidirectional, SQ-MELF","metaDescription":"1N6115US from Microchip Technology: Zener TVS diode, 500W peak pulse power, bidirectional, 18.2V reverse standoff, 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, B","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"1N6115","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)":"21.66V","Voltage - Clamping (Max) @ Ipp":"34.97V","Voltage - Reverse Standoff (Typ)":"18.2V","Current - Peak Pulse (10/1000µs)":"14.25A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.2400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5dbd5050221203b922ebce5a7a6e86e6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1N6115US bidirectional?","answer":"Yes, the 1N6115US has one bidirectional channel, meaning it clamps transients of either polarity symmetrically."},{"question":"What is the peak pulse power rating of the 1N6115US?","answer":"The 1N6115US is rated for 500 W peak pulse power under the 10/1000 µs waveform condition."},{"question":"What package does the 1N6115US come in?","answer":"It is supplied in an SQ-MELF B package (surface-mount, cylindrical MELF style), supplied in Bulk packaging."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6115US","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6115US when reusing this data.
