It is AEC-Q101 qualified for automotive applications and targets Ethernet PHY interfaces where low clamping voltage and fast response are critical. With a reverse standoff voltage of 5.25 V typical, the USBLC6-4SC6Y sits above the 3.3 V supply rail common on automotive Ethernet PHYs, so it does not clip normal signal levels. Breakdown starts at 6 V minimum, and clamping is held to 17 V maximum at the peak pulse current of 5 A (8/20 µs waveform). That 17 V ceiling keeps the downstream transceiver within its absolute-maximum input rating during a coupled surge. ## Automotive temperature range and qualification The six-pin layout routes the four protected channels between the supply and ground rails — the centre pins are typically the common rail connections.","metaTitle":"USBLC6-4SC6Y Steering TVS, AEC-Q101, SOT-23-6","metaDescription":"STMicroelectronics USBLC6-4SC6Y rail-to-rail steering TVS, AEC-Q101 qualified, 5.25V reverse standoff, 17V clamp, SOT-23-6.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Steering (Rail to Rail)","Grade":"Automotive","Series":"USBY","Package":"Tape & Reel (TR) Cut Tape (CT)","Applications":"Ethernet","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"SOT-23-6","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"-","Base Product Number":"USBLC6","Operating Temperature":"-40°C ~ 125°C (TJ)","Power Line Protection":"Yes","Capacitance @ Frequency":"-","Supplier Device Package":"SOT-23-6","Unidirectional Channels":"4","Voltage - Breakdown (Min)":"6V","Voltage - Clamping (Max) @ Ipp":"17V","Voltage - Reverse Standoff (Typ)":"5.25V","Current - Peak Pulse (10/1000µs)":"5A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e83ab56541ab856f8f429a8db0d55c50.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/USBLC6-4SC6Y/alternatives.json"},"ai":{"faq":[{"question":"Is USBLC6-4SC6Y AEC-Q101 qualified?","answer":"Yes, the USBLC6-4SC6Y is AEC-Q101 qualified, making it suitable for automotive-grade applications requiring documented reliability testing."},{"question":"What package does USBLC6-4SC6Y come in?","answer":"It comes in a SOT-23-6 surface-mount package, also listed as the supplier device package SOT-23-6."},{"question":"What is the USBLC6-4SC6Y?","answer":"The USBLC6-4SC6Y is a rail-to-rail steering TVS diode array from STMicroelectronics, part of the USBY series, designed to protect four unidirectional data lines on Ethernet interfaces in automotive applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/USBLC6-4SC6Y","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/USBLC6-4SC6Y when reusing this data.
