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 ESD (electrostatic discharge), EFT (electrical fast transients), and lightning.

Features
◆ ESD protection to IEC 61000-4-2, Level 4
◆ Array of surge rated diodes with internal TVS Diode
◆ Protects two I/O lines
◆ Low capacitance (<10pF) for high-speed interfaces
◆ Low clamping voltage
◆ Low operating voltage: 5.0V
◆ Solid-state silicon-avalanche technology

Applications
◆ USB Power & Data Line Protection
◆ Ethernet 10BaseT
◆ I2C Bus Protection
◆ Video Line Protection
◆ T1/E1 secondary IC Side Protection
◆ Portable Electronics
◆ Microcontroller Input Protection
◆ WAN/LAN Equipment
◆ ISDN S/T Interface
