Ultra-Low Capacitance TVS for EDS and CDE Protection

Add to Watch List

RailClamps are 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)
  • Designed to replace polymer TVS
  • Protects up to two I/O lines
  • Ultra-Low Line-to-Line capacitance (<0.5pF Typical)
  • No insertion loss to >3.0GHz
  • Low profile (<1mm)
  • Low leakage current and clamping voltage
  • Low operating voltage: 24.0V
  • Solid-state silicon-avalanche technology
  • RoHS/WEEE compliant


  • High-Definition Multimedia Interface (HDMI)
  • USB 2.0 & Firewire Ports
  • GaAs Photodetector Protection
  • HBT Power Amp Protection
  • Infiniband Transceiver Protection
