RailClamp® 低容TVS阵列


The RailClamp® series consists of ultra low capacitance TVS arrays designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients).


  • Transient protection for high-speed data lines to IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns)
  • Flow through design for ease of layout for high speed data line application
  • Protects up to two I/O lines & power line
  • Low capacitance (<0.9pF) for high-speed interfaces
  • Ultra-small package requires less than 2.9mm² of PCB area
  • Low leakage current and clamping voltage
  • Low operating voltage: 5.0V
  • Solid-state silicon-avalanche technology


  • USB 2.0 High Speed
  • 10/100/1000 Ethernet Ports
  • High-Definition Multimedia Interface (HDMI)
  • Digital Visual Interface (DVI)
  • Monitors and Flat Panel Displays
  • Video Graphics Cards
  • IEEE 1394 Firewire Ports High Speed
