Description
Features
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 RClampTM0544M has a typical capacitance of only
0.30pF. 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.
