  • IEC 61000-4-4 (EFT) 40A (5/50 ns)
  • Package optimized for high-speed lines
  • Low capacitance: 0.25pF (typical)
  • Low leakage current
  • Low clamping voltage
  • Meet MSL level1
  • Halogen free and RoHS compliant
  • Series ATA
  • Desktops, Servers and Notebooks
  • Cellular Phones
  • MDDI Ports
  • USB Data Line Protection
  • Display Ports
  • Digital Visual Interfaces (DVI)
