RailClamps are surge rated diode arrays designed to

protect high speed data interfaces. The SR series has

been specifically designed to protect sensitive compo-

nents which are connected to data and transmission

lines from overvoltage caused by electrostatic dis-

charge (ESD), electrical fast transients (EFT), and

tertiary lightning.

The unique design of the SR series devices incorpo-

rates four surge rated, low capacitance steering

diodes, and a TVS diode in a single package. The TVS

diode is constructed using Semtech’s proprietary low

voltage EPD technology for superior electrical charac-

teristics at 2.8 volts.

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 low capacitance array configuration allows the user

to protect two high-speed data or transmission lines.

The low inductance construction minimizes voltage

overshoot during high current surges.
