RClamp®0542Z is an ultra low capacitance ESD protec-
tion device designed to protect two high-speed lines in
an 0201 footprint. This revolutionary package design
reduces board space requirements by more than 50%
over existing single line solutions. RClamp0542Z is a
three pin device with identical low capacitance TVS di-
odes connected to each pin. Any two pins may be con-
nected to high-speed lines, while the third pin is con-
nected to ground. This gives the designer maximum flex-
ibility in pcb routing. Each line has a maximum capaci-
tance of only 0.30pF allowing it to be used on circuits
operating in excess of 6GHz without appreciable signal
attenuation.
RClamp0542Z is in a 3-pin SLP0603P3X3A package.
It measures 0.62 x 0.32 mm with a nominal height of
only 0.25mm. Leads partially extend up the side of the
package for ease of soldering and are finished with
lead-free NiAu. 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 tablets.

Assembly Guidelines
The small size of this device means that some care
must be taken during the mounting process to insure
reliable solder joints. The figure at the right details
Semtech’s recommended aperture based on the
assembly guidelines detailed in the table below. 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.
Exact manufacturing parameters will require some
experimentation to get the desired solder application.
