Semtech SRDA70-4

RailClamp® 500瓦低容15 pF / 线阵列


RailClamps are surge rated diode arrays designed to protect high speed data interfaces. The SRDA70-4 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 61000-4-4 (EFT) 40 A (5/50 ns)
    • IEC 61000-4-5 (lightning) 1 kV, 24 A (8/20 µs)
  • Array of surge-rated diodes
  • Protects four I/O lines
  • Low capacitance for high-speed interfaces
  • High surge capability
  • Low forward voltage characteristics
  • Solid-state silicon-avalanche technology


  • Latch-up protection
  • Microcontroller input protection
  • Token ring
  • I2C bus protection
  • Video line protection
  • Set-top box I/O
  • LAN/WAN equipment
