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 with a nomi-
nal height of 0.58mm. The RClamp0524P is in a 10-pin,
RoHS/WEEE compliant, SLP2510P8 package. It mea-
sures 2.5 x 1.0 with a nominal height of 0.58mm. The
leads are spaced at a pitch of 0.5mm 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 combination of small size, low capacitance,
and high level of ESD protection makes them a flexible
solution for applications such as HDMI, DisplayPort
TM
,
MDDI, and eSATA interfaces.
