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
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 characteristics at
3.3 volts.
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 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.
