PROTECTION PRODUCTS - RailClamp^®
Description
The RailClamp^® series is a family of ultra low capaci-
tance TVS arrays 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).
They are designed for use in applications where board
space is at a premium. Each device requires less than
1.2mm² of PCB area and will protect up to two high
speed data lines.
The monolithic design incorporates surge rated, low
capacitance steering diodes and a TVS diode in a single
package. Each line has a typical capacitance of
<0.5pF to ground. The capacitance of each line is well
matched for consistant signal balance. A connection
to the TVS is provided for protection of external
voltage buses, such as those found in USB applica-
tions. This device is optimized for ESD protection of
portable electronics. They may be used to meet the
ESD immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge).
The RClamp0502N is in a 6-pin, RoHS/WEEE compli-
ant, SLP1210N6 package. It measures 1.2 x 1.0 x
0.58mm. The small package makes it ideal for use in
portable electronics such as cell phones, laptops, and
digital still cameras.
