PROTECTION PRODUCTS - RailClamp®
Features
Description
RailClamp® is a low capacitance TVS array designed to
protect high speed data interfaces. This series has been
specifically designed to protect sensitive components
which are connected to data and transmission lines from
overvoltage caused by ESD (electrostatic discharge), CDE
(Cable Discharge Events), and EFT (electrical fast tran-
sients).
Transient protection for high-speed data lines to
IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
IEC 61000-4-4 (EFT) 40A (5/50ns)
Array of surge rated diodes with internal TVS Diode
Small package saves board space
Protects up to four I/O lines
Low capacitance (<0.8pF) for high-speed interfaces
Minimal insertion loss to 3.0GHz
The monolithic design incorporates surge rated, low
capacitance steering diodes and a TVS diode in a single
package. Each line has a maximum capacitance of
< 0.8pF to ground. The capacitance of each line is well
matched for consistant signal balance. This device is
optimized for ESD protection of portable electronics. It
may be used to meet the ESD immunity requirements
of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact
discharge).
The RClampTM2504P and RClampTM3304P are con-
structed using Semtech’s proprietary EPD process
technology. The EPD process provides low standoff
voltages with significant reductions in leakage current
and capacitance over silicon-avalanche diode pro-
cesses. They feature a true operating voltage of 2.5
volts and 3.3 volts for superior protection.
Low operating voltage: 2.5V and 3.3V

Applications Information
Device Connection for Protection of Four High-Speed
Data Lines
Figure 1. Pin Configuration (Top Side View)
These devices are designed to protect low voltage data
lines operating at 2.5 volts or 3.3 volts. When the
voltage on the protected line exceeds the TVS working
voltage, the steering diodes are forward biased,
conducting the transient current away from the
sensitive circuitry, through the internal TVS to ground.
Data lines are connected at pins 1, 2, 5 and 6. The
center pin should be connected directly to a ground
plane. The path length is kept as short as possible to
minimize parasitic inductance. For best results,
multiple micro-vias connected to ground are

recommended. Pins 3 and 4 are not connected.
Note that pin 3 is connected internally to the cathode
of the low voltage TVS. However, due to the snap-
back characteristics of the EPD TVS, this pin should
not be directly connected to a DC supply voltage.
