PPRROOTTEECCTTIIOONN PPRROODDUUCCTTSS - RailClamp®
Description
RailClamp is an ultra low capacitance Transient Voltage
Suppressor (TVS) designed to protect high speed data
interfaces. This device has been specifically designed
to protect sensitive components which are connected
to high-speed data and transmission lines from over-
voltage caused by ESD (electrostatic discharge), CDE
(Cable Discharge Events), and EFT (electrical fast
transients).
The RClampTM0531T has a maximum capacitance of
only 0.80pF. This allows it to be used on circuits
operating in excess of 2.5GHz without signal attenua-
tion. They may be used to meet the ESD immunity
requirements of IEC 61000-4-2.
The RClamp0531T is in a 2-pin SLP1006P2T package
measuring 1.0 x 0.6 x 0.4mm. The leads are spaced
at a pitch of 0.65mm and feature a lead-free finish.
Each device will protect one high-speed line operating
at 5 volts. It gives the designer the flexibility to protect
single lines in applications where arrays are not practi-
cal. The combination of small size, low capacitance,
and high ESD surge capability makes them ideal for
use in applications such as cellular phones and digital
video interfaces.

Applications Information
Device Connection Options
These low capacitance TVS diodes are designed to
provide common mode protection for one high-speed line
or differential protection for one line pair. The device is
bidirectional and may be used on lines where the signal
polarity is positive and negative.
Circuit Board Layout Recommendations for Suppres-
sion of ESD.
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:
z Place the TVS near the input terminals or connec-
tors to restrict transient coupling.
z Minimize the path length between the TVS and the
protected line.
z Minimize all conductive loops including power and
ground loops.
z The ESD transient return path to ground should be
kept as short as possible.
z Never run critical signals near board edges.
z Use ground planes whenever possible.
