USBLC6-2SC6

USBLC6-2SC6 is a monolithic ESD protection device from STMicroelectronics in SOT23-6L, protecting two data lines plus VBUS for high-speed interfaces such as USB 2.0, Ethernet links, and video lines. Its advantage is signal integrity without compromise: 3.5 pF maximum line capacitance, 150 nA maximum leakage current, 0.015 pF capacitance matching tolerance between I/O and ground, and IEC 61000-4-2 level 4 protection of 15 kV air discharge and 8 kV contact discharge guaranteed at device level. The business gain is fewer field returns and cleaner compliance: one tiny 9 sq mm device guards the port that users touch, while low leakage stretches battery life in portable products and monolithic integration keeps clamping consistent across lines. Evidence: ST official product pages list this order code as Active and confirm the 3.5 pF capacitance, 150 nA leakage, IEC 61000-4-2 level 4 ratings, and SOT23-6L tape-and-reel packing. Selection advice: the SC6 suffix denotes SOT23-6L; the same silicon ships as USBLC6-2P6 in the smaller SOT-666 package, so pick SC6 when hand inspection and rework matter and P6 when board space is tight, and do not substitute the automotive USBLC6-2SC6Y variant without checking its AEC-Q101 qualification and different ESD ratings against your requirement.
