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

lightning.

The unique design of the SRDA series devices incorpo-

rates surge rated, low capacitance steering diodes and

a TVS diode in a single package. During transient

conditions, the steering diodes direct the transient to

either the positive side of the power supply line or to

ground. The internal TVS diode prevents over-voltage

on the power line, protecting any downstream compo-

nents.

The low capacitance array configuration allows the user

to protect six high-speed data or transmission lines.

The low inductance construction minimizes voltage

overshoot during high current surges.
