RailClamps are surge rated diode arrays designed to protect high speed data interfaces. The SR2.8 has been specifically designed to protect sensitive compo-nents which are connected to data and transmission lines from overvoltage caused by ESD (electrostaticdischarge), EFT  (electrical fast transients), and tertiary lightning.

The unique design of the SR2.8 devices incorpo-rates four surge rated, low capacitance steering diodes and a TVS diode in a single package.  The SR2.8 is constructed using Semtech's proprietary low voltage EPD technology for superior electrical characteristics at 2.8 volts.

During transient conditions, the SR2.8 direct the transient to either the positive side of the power supply line or to ground.  The internal TVS diode pre-vents over-voltage on the power line, protecting any downstream components.

The SR2.8 allows the user to protect two high-speed data or transmission lines.The low inductance construction minimizes voltage overshoot during high current surges
