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 six I/O lines and power supply line
◆ Low capacitance (<15pF) for high-speed interfaces
◆ Low operating & clamping voltages
◆ Solid-state technology
