PROTECTION PRODUCTS - Z-PakTM
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.
RClamp®1821Z has a maximum capacitance of only
0.8pF. This allows it to be used on circuits operating in
excess of 3GHz without signal attenuation.
RClamp1821Z is in a 2-pin SLP0603P2X3B 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 18 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.
