Description
PRELIMINARY
Features
 Transient protection for data lines to
RailClamp® TVS arrays are ultra low capacitance ESD
protection devices designed to protect high speed
data interfaces. This series 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).



RClamp®0551P has a maximum capacitance of
0.50pF. This allows it to be used on circuits operating
in excess of 5GHz without appreciable signal attenuation. They exceed the ESD immunity requirements of
IEC 61000-4-2, Level 4.


RClamp0551P is in a 2-pin SLP1006P2 package
measuring 1.0 x 0.6 x 0.5mm. 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.

Equivalent Circuit Diagram
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:
 Place the TVS near the input terminals or connectors to restrict transient coupling.
 Minimize the path length between the TVS and the
protected line.
 Minimize all conductive loops including power and
ground loops.
 The ESD transient return path to ground should be
kept as short as possible.
 Never run critical signals near board edges.
 Use ground planes whenever possible.
