FEATURES
• ESD IEC 61000-4-2 level 4,
± 8kV contact discharge compliant protection
• Four ultra-low input capacitance (1 pF typ.)
ESD rail-to-rail protection diode s
• Low voltage clamping due to integrated Zener
diode
• Small 6 lead SO6 (SOT457) package
APPLICATIONS
General-purpose downstream ESD protection high
frequency analog signal s and high-speed serial data
transmission for ports inside:
• Cellular and PCS mobile handsets
• PC-/Notebook USB2.0/IEEE1394 ports
• DVI interfaces
• Cordless telephones
• Wireless data (WAN/LAN) systems
• PDAs
DESCRIPTION
The IP4220CZ6 is designed to prote ct I/Os bei ng
sensitive concerning capa citive load, su ch as
USB 2.0, Ethernet, DVI etc. from destruction by
Electro Static Discharges (ESD).
Therefore, the IP4220CZ6 incorporates four pairs of
ultra-low capacity rail-to-rail diodes plus an
additional Zener diode to provide prote ction to
downstream signal and supply components from
Electrostatic Discharge (ESD) voltages as high as
±8 kV contact discharge.
Due to the rail-to-rail diodes being co nnected to the
Zener diode, the protection is working independent
form the availability of a supply voltage.
The IP4220CZ6 is fabricated usi ng thin film-on-
silicon technology and integrates 4 ultra-low cap acity
rail-to-rail ESD protection diodes in a m iniature
6-lead SOT457 package.
