RailClamps are ultra low capacitance TVS arrays
designed to protect high speed data interfaces. This
series has been specifically designed to protect sensi-
tive 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 RClamp
0.50pF (pin 1 to 2). This means it can be used on
circuits operating in excess of 3GHz without signal
attenuation. They may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge). Each device can
be configured to protect 1 bidirectional line or two
unidirectional lines.
These devices are in a small SC-75 (SOT-523) package
and feature a lead-free, matte tin finish. They are com-
patible with both lead free and SnPb assembly tech-
niques. They are designed for use in applications where
board space is at a premium. The combination of small
size, low capacitance, and high level of ESD protection
makes them a flexible solution for applications such as
HDMI, MDDI, antenna circuits, Automatic Test Equipment,
USB 2.0, and Infiniband circuits.
