PROTECTION PRODUCTS - RailClamp®
Description
Features
‹ Transient protection for data lines to
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 overvoltage caused by ESD (electrostatic discharge), CDE
(Cable Discharge Events), and EFT (electrical fast
transients).
The RClampTM0531TQ has a maximum capacitance of
only 0.80pF. This allows it to be used on circuits
operating in excess of 2.5GHz without signal attenuation. They may be used to meet the ESD immunity
requirements of IEC 61000-4-2.

The RClamp0531TQ 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 practical. 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.
The RClamp0531TQ is AEC-Q100 Grade 1 qualified for
Automotive use.

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 Suppression 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 connectors 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.
