Semtech RClamp0508M

RailClamp® Low-Capacitance TVS Diode Array

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