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.

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) 0.5kV, 12A (8/20µs)
◆ Array of surge rated diodes with internal TVS Diode
◆ Protects two I/O lines
◆ Operating Voltage: 12 volts
