Description
RClamp arrays are ultra low capacitance ESD
protection devices 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 RClamp0522P and RClamp0524P 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. The RClamp0522P is designed to protect two
lines, while the RClamp0524P will protect four lines.
The RClamp0522P is in a 6-pin SLP1610P4 package. It
measures 1.6 x 1.0 with a nominal height of 0.58mm.
The RClamp0524PA is in a 10-pin SLP2510P8 package.
It measures 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,
DisplayPortTM, MDDI, and eSATA interfaces.
