PROTECTION PRODUCTS
Description
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.
