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.
