The 29.7V reverse standoff means it stays out of the way on a 24V rail, but when a transient comes, it shunts the energy before the downstream silicon sees the overvoltage. On the repair bench, a scorched SQ-MELF package with a shorted junction tells you the surge exceeded the part's energy rating – check the upstream source before swapping. ## SQ-MELF package – footprint and thermal path Housed in a C, SQ-MELF surface-mount package, the 1N6156AUS sits on a solder pad that doubles as the thermal path.","metaTitle":"1N6156AUS Zener TVS Diode – 1.5kW, SQ-MELF, Active","metaDescription":"1N6156AUS from Microchip Technology: Zener TVS diode, 1500W peak pulse power, 29.7V standoff, 53.6V clamp, 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","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6156","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)":"37.1V","Voltage - Clamping (Max) @ Ipp":"53.6V","Voltage - Reverse Standoff (Typ)":"29.7V","Current - Peak Pulse (10/1000µs)":"28A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$21.6000","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6156AUS/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6156AUS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6156AUS when reusing this data.
