The 30.1A peak pulse current handles the energy from a typical industrial transient without entering secondary breakdown. ## Active production, Tape & Reel delivery Microchip lists the 1N6155AUS/TR as Active. It ships in Tape & Reel in the SQ-MELF, C package — a surface-mount ceramic body with a cylindrical footprint. Sourced and quoted per RFQ against BOM quantities.","metaTitle":"1N6155AUS/TR Zener TVS Diode – 1500W, 27.4V Standoff","metaDescription":"1N6155AUS/TR from Microchip Technology: 1500W peak pulse power, 27.4V reverse standoff, 34.2V breakdown min, 49.9V clamp, 30.1A Ipp.","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, C","Product Status":"Active","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)":"34.2V","Voltage - Clamping (Max) @ Ipp":"49.9V","Voltage - Reverse Standoff (Typ)":"27.4V","Current - Peak Pulse (10/1000µs)":"30.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$20.2201","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6155AUS%2FTR/alternatives.json"},"ai":{"faq":[{"question":"Can 1N6155AUS/TR be used on a 24V DC bus?","answer":"Yes. The reverse standoff voltage is 27.4V, which is 3.4V above a nominal 24V rail. The breakdown minimum of 34.2V ensures the device does not conduct during normal operation, while clamping at 49.9V limits the transient to a safe level for downstream silicon rated at 60V or higher."},{"question":"Is 1N6155AUS/TR unidirectional or bidirectional?","answer":"Bidirectional — one channel clamps both positive and negative surges. This eliminates the need for two unidirectional parts in series, simplifying PCB layout and reducing component count."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6155AUS-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6155AUS-TR when reusing this data.
