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.
RClamp®0521Z has a typical capacitance of only
0.35pF. This allows it to be used on circuits operating
in excess of 5GHz without appreciable signal attenua-
tion.
RClamp0521Z is in a 2-pin SLP0603P2X3 package. It
measures 0.6 x 0.3 mm with a nominal height of only
0.25mm. Leads are finished with lead-free NiAu. Each
device will protect one line operating at 5 volts. It
gives the designer the flexibility to protect single lines in
applications where arrays are not practical. 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.

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.
