RailClamp® Ultra Low Capacitance TVS Arrays

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).


  • ESD protection for high-speed data lines to
  • IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
  • IEC 61000-4-5 (Lightning) 5A (8/20μs)
  • IEC 61000-4-4 (EFT) 40A (5/50ns)
  • Package design optimized for high speed lines
  • Protects four I/O lines
  • Low capacitance: 0.3pF typical (I/O to I/O)
  • Low clamping voltage
  • Low operating voltage: 5V


  • Cell Phones and Accessories
