Its two unidirectional channels match the D+ and D- pair on a USB port, shunting overvoltage to the supply rails without loading the signal path during normal operation. ## Clamping voltage and breakdown margins With a reverse standoff voltage of 5.25 V and a minimum breakdown of 6 V, the USBLC6-2P6 sits just above the 5 V USB bus voltage — it stays transparent during normal signalling but triggers before the downstream transceiver sees damage. The clamping voltage is 17 V at a peak pulse current of 5 A (8/20 µs waveform), which keeps the let-through voltage within the absolute maximum ratings of most USB 2.0 PHYs. The SOT-666 package (1.6 mm × 1.2 mm body) fits tight PCB layouts near the USB connector; the 0.50 mm pitch demands careful solder-paste stencil design to avoid bridging.","metaTitle":"STMicroelectronics USBLC6-2P6 Steering (Rail to Rail) ESD","metaDescription":"STMicroelectronics USBLC6-2P6 steering (rail to rail) ESD protection array, 2 unidirectional channels, 5.25V reverse standoff, 17V clamping, SOT-666.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Steering (Rail to Rail)","Series":"USB","Package":"Tape & Reel (TR) Cut Tape (CT)","Applications":"USB","Mounting Type":"Surface Mount","Package / Case":"SOT-563, SOT-666","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"-","Base Product Number":"USBLC6","Operating Temperature":"-40°C ~ 150°C (TJ)","Power Line Protection":"Yes","Capacitance @ Frequency":"-","Supplier Device Package":"SOT-666","Unidirectional Channels":"2","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":"$0.32407","priceTiers":[{"qty":5,"price":"$0.32407","currency":"USD"},{"qty":50,"price":"$0.25616","currency":"USD"},{"qty":150,"price":"$0.22303","currency":"USD"},{"qty":500,"price":"$0.19349","currency":"USD"},{"qty":3000,"price":"$0.17884","currency":"USD"},{"qty":6000,"price":"$0.17395","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/56fad751c49dead85d767d929ef48c5f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/USBLC6-2P6/alternatives.json"},"ai":{"faq":[{"question":"Does USBLC6-2P6 work for USB 2.0 ESD protection?","answer":"Yes. The two unidirectional channels align with the D+ and D- lines of a USB 2.0 port. The 5.25 V reverse standoff sits above the 5 V bus voltage, and the 17 V clamping at 5 A peak pulse keeps the let-through within the PHY's tolerance. The rail-to-rail steering topology also handles the 480 Mbps data rate without adding significant capacitance."},{"question":"What is the replacement or equivalent for USBLC6-2P6?","answer":"No official replacement or pin-compatible equivalent is listed in the manufacturer cross-reference for the USBLC6-2P6. The base product number is USBLC6; any alternate would need to match the SOT-666 footprint, 2-channel rail-to-rail topology, and 5.25 V standoff voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/USBLC6-2P6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/USBLC6-2P6 when reusing this data.
