PROTECTION PRODUCTS - RailClamp^
Description
RailClamps^ are surge rated diode arrays designed to
protect high speed data interfaces. This series has
been specifically designed to protect sensitive compo-
nents which are connected to data and transmission
lines from overvoltage caused by ESD (electrostatic
discharge), CDE (Cable Discharge Events), and EFT
(electrical fast transients).
The unique design 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 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. This device is
optimized for ESD protection of portable electronics.
They may be used to meet the ESD immunity require-
ments of IEC 61000-4-2, Level 4 (±15kV air, ±8kV
contact discharge).
