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 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).
The RClamp^®0544T has a typical capacitance of only
0.30pF between I/O pins. This allows it to 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. Each device
is designed to protect four lines (two differential pairs).
The RClamp0544T is in an 8-pin SLP2010P8T package.
It measures 2.0 x 1.0 x 0.4mm. The leads are spaced at
a pitch of 0.4mm and are finished with lead-free NiPdAu.
They are designed for easy PCB layout by allowing the
traces to run straight through the device. The combina-
tion of small size, low capacitance, and high level of ESD
protection makes them a flexible solution for applica-
tions such as mini HDMI, MDDI, USB, and eSATA inter-
faces.
