PROTECTION PRODUCTS - RailClamp®
Description
RailClamp® TVS arrays are ultra low capacitance ESD
protection devices designed to protect high speed data
interfaces. They are designed to replace 0201 size mul-
tilayer varistors (MLVs) in portable applications such as
cell phones, notebook computers, and other portable
electronics. This device offers desirable characteristics
for board level protection including fast response time,
low operating and clamping voltage, and no device deg-
radation.
The RClamp®0552T has a maximum capacitance of
only 0.40pF. This allows it to be used on circuits
operating in excess of 5GHz without signal attenuation.
The RClamp0552T is in a 3-pin SLP1006N3T package.
It measures 1.0 x 0.6 mm with a nominal height of only
0.4mm. The leads are finished with lead-free NiPdAu.
Each device will protect two lines operating at 5 volts.
It gives the designer the flexibility to replace multiple
single line devices in space constrained applications.
They may be used to meet the ESD immunity require-
ments of IEC 61000-4-2. The combination of small
size and high ESD surge capability makes them ideal
for use in portable applications such as cellular
phones, digital cameras, and MP3 players.

Applications Information
Device Connection Options
The RClamp0552T is designed to protect two high-
speed data lines operating up to 5 volts. The device is
bidirectional and may be used on lines where the signal
polarity is above and below ground. The diagram at the
right shows an example pin configuration with pin 3
connected to ground. However, due to the device
symmetry, any pin may be connected to ground with
the remaining pins conneted to the protected lines.
Assembly Guidelines
The small size of this device means that some care
must be taken during the mounting process to insure
reliable solder joint. The table below provides
Semtech's recommended assembly guidelines for
mounting this device. The figure at the right details
Semtech’s recommended aperture based on the
below recommendations. Note that these are only
recommendations and should serve only as a starting
point for design since there are many factors that
affect the assembly process. The exact manufactur-
ing parameters will require some experimentation to
get the desired solder application.
