RailClamp® Low Capacitance TVS Diode Array

Add to Watch List

RailClamps are surge rated diode arrays designed to protect high speed data interfaces. The SR series has been specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning.


  • Transient protection for high-speed data lines to
    • IEC 61000-4-2 (ESD) ± 15 kV (air), ± 8 kV (contact)
    • IEC 61000-4-4 (EFT) 40 A (5/50 ns)
    • IEC 61000-4-5 (Lightning) 24 A (8/20 µs)
  • Array of surge-rated diodes with internal TVS diode
  • Protects six I/O lines and power supply line
  • Low capacitance (< 15 pF) for high-speed interfaces
  • Low operating & clamping voltages
  • Solid-state technology


  • USB power & data line protection
  • T1/E1 secondary IC side protection
  • Token ring
  • HDSL, SDSL secondary IC side protection
  • Video line protection
  • Microcontroller input protection
  • Base stations
  • I2C bus protection
