RailClamps are surge rated diode arrays designed to
protect high speed data interfaces. The RClamp series
has been specifically designed to protect sensitive
components which are connected to data and trans-
mission lines from overvoltage caused by ESD (electro-
static discharge), CDE (cable discharge events), EFT
(electrical fast transients), and lightning.
The unique design of these devices incorporates 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 components.
The RClamp
3pF and may be used on lines operating up 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 eight 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 discharge).
