PROTECTION PRODUCTS - RailClamp
Description
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
TM
0514M has a typical capacitance of only
0.70pF (I/O to I/O). This means it can be used on
circuits operating in excess of 2GHz 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).
These devices are in a MSOP 10L package and feature a
lead-free, matte tin finish. They are compatible with both
lead free and SnPb assembly techniques. They are de-
signed for easy PCB layout by allowing the traces to run
straight through the device. The combination of small
size, low capacitance, and high level of ESD protection
makes them a flexible solution for protecting high-speed
HDMI and DVI video interfaces.
