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 SR series devices incorpo-
rates eight 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 down-
stream components.
The SRV05-4 has a low typical capacitance of 3pF and
operates with virtually no insertion loss to 1GHz. This
makes the device ideal for protection of high-speed
data lines such as USB 2.0, Firewire, DVI, and gigabit
Ethernet interfaces.
The low capacitance array configuration allows the user
to protect four high-speed data or transmission lines.
The low inductance construction minimizes voltage
overshoot during high current surges. They may be
used to meet the ESD immunity requirements of IEC
61000-4-2, Level 4 (±15kV air, ±8kV contact dis-
charge).
