RailClamp® Low-Capacitance TVS Diode Array

加入关注列表

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 tertiary lightning.

Features


  • ESD protection to
    • IEC 61000-4-2 (ESD) ± 15 kV (air), ± 8 kV (contact)
    • IEC 61000-4-4 (EFT) 40 A (5/50 ns)
  • Array of surge-rated diodes with internal EPD TVS diode
  • Protects two I/O lines
  • Low capacitance (< 10 pF) for high-speed interfaces
  • Low leakage current (< 1 µA)
  • Low operating voltage: 3.3 V
  • Solid-state technology

Applications


  • Data and I/O lines
  • Sensitive analog inputs
  • Video line protection
  • Portable electronics
  • Microcontroller input protection
  • WAN/LAN equipment
