Description

RailClamps are surge rated diode arrays designed to protect high speed data interfaces. The SR12 has been specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltages caused by ESD (electrostatic discharge), EFT (electrical fast transients), and lightning.
