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
TM
0522P and RClamp
TM
0524P have 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,
Level 4 (±15kV air, ±8kV contact discharge). The
RClamp0522P is designed to protect two lines, while the
RClamp0524P will protect four lines.
The RClamp0522P is in a 6-pin, RoHS/WEEE compliant,
SLP1610P4 package. It measures 1.6 x 1.0 x 0.58mm.
The RClamp0524P is in a 10-pin, RoHS/WEEE compliant,
SLP2510P8 package. It measures 2.5 x 1.0 x 0.58mm.
The leads are spaced at a pitch of 0.5mm and are
fi
nished
with lead-free NiPd. They are designed 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
fl
exible solution for
applications such as HDMI, UDI, DisplayPort
TM
, MDDI, Serial
ATA, and Infiniband circuits.
