Product profile

1.1 General description

The IP4233CZ6 is designed to protect Input/Output (I/O) ports that are sensitive to

capacitive loads, such as Ethernet, from destruction by ElectroStatic Discharge (ESD).

The IP4233CZ6 incorporates two pairs of ultra low capacitance back-to-back diodes

which protect components from ESD voltages as high as

±8 kV contact discharge

according to IEC 61000-4-2, level 4.

The back-to-back diodes prevent negative clipping of AC signals and voltages below zero.

The IP4233CZ6 is fabricated using monolithic silicon technology integrating two ultra low

capacitance back-to-back ESD protection diodes in a very small 6-lead SOT363 package.
