Semtech SRDA70-4

Semtech SRDA70-4

RailClamp® 500 Watt Low-Capacitance 15 pF / Line Array

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.

Features

  • 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) 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

Applications
