DESCRIPTION
The IP4220CZ6 is designed to protect I/Os being
sensitive concerning capacitive load, such 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 protection 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 connected to the
Zener diode, the protection is working independent
form the availability of a supply voltage.
The IP4220CZ6 is fabricated using thin film-on-
silicon technology and integrates 4 ultra-low capacity
rail-to-rail ESD protection diodes in a miniature
6-lead SOT457 package.
