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
TM
0524J 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,
Level 4 (±15kV air, ±8kV contact discharge). Each
device is designed to protect four lines (two differential
pairs).
The RClamp0524J is in a 8-pin, RoHS/WEEE compliant,
SLP2710P8 package. It measures 2.7 x 1.0 x 0.58mm.
The leads are spaced at a pitch of 0.5mm and are fin-
ished 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 capaci-
tance, and high level of ESD protection makes them a
flexible solution for applications such as HDMI,
DisplayPort
TM
, MDDI, and eSATA interfaces.
