The USBLC6-2SC6 and USBLC6-2P6 are monolithic application specific devices dedicated to ESD protection of high speed interfaces, such as USB 2.0, Ethernet links and video lines.

The very low line capacitance secures a high level of signal integrity without compromising in protecting sensitive chips against the most stringently characterized ESD strikes.

Key Features

  • 2 data-line protection
  • Protects VBUS
  • Very low capacitance: 3.5 pF max.
  • Very low leakage current: 150 nA max.
  • SOT-666 and SOT23-6L packages
  • RoHS compliant
  • Benefits
    • Very low capacitance between lines to GND for optimized data integrity and speed
    • Low PCB space consumption: 2.9 mm2 max for SOT-666 and 9 mm² max for SOT23-6L
    • Enhanced ESD protection: IEC 61000-4-2 level 4 compliance guaranteed at device level, hence greater immunity at system level
    • ESD protection of VBUS
    • High reliability offered by monolithic integration
    • Low leakage current for longer operation of battery powered devices
    • Fast response time
    • Consistent D+ / D- signal balance:
      • Very low capacitance matching toleranceI/O to GND = 0.015 pF
      • Compliant with USB 2.0 requirements
  • Complies with the following standards:
    • IEC 61000-4-2 level 4:
      • 15 kV (air discharge)
      • 8 kV (contact discharge)
