Description

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.

Features

◆ Transient protection for high-speed data lines to IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) IEC 61000-4-5 (Lightning) 24A (8/20µs)

◆ Array of surge rated diodes with internal TVS diode

◆ Protects four I/O lines and power supply line

◆ Low capacitance (<15pF) for high-speed interfaces

◆ Low operating and clamping voltages

◆ Solid-state technology

Applications

◆ USB Power and Data Line Protection

◆ T1/E1 secondary IC Side Protection

◆ T3/E3 secondary IC Side Protection

◆ HDSL, SDSL secondary IC Side Protection

◆ Video Line Protection

◆ Microcontroller Input Protection

◆ Base stations

◆ I2C Bus Protection
