That means a 5V rail sees the diode clamp at roughly double the nominal voltage during a surge — enough to keep downstream 5V-rated ICs inside their absolute-maximum ratings if the PCB layout keeps trace inductance low. ## Active production — no obsolescence risk The base product number is 1N6103, so variants with different screening levels or lead finishes share the same die.","metaTitle":"1N6103US Zener TVS Diode – 500W, 5.7V Standoff, SQ-MELF","metaDescription":"1N6103US bidirectional Zener TVS from Microchip. 500W peak pulse power, 5.7V reverse standoff, 6.77V min breakdown, SQ-MELF package.","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":"1N6103","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)":"6.77V","Voltage - Clamping (Max) @ Ipp":"11.76V","Voltage - Reverse Standoff (Typ)":"5.7V","Current - Peak Pulse (10/1000µs)":"42.37A"}},"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/1N6103US","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6103US when reusing this data.
