IP4233CZ6
Ultra low capacitance ESD protection for Ethernet ports
Rev. 3 — 17 June 2010
Product data sheet
1. 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.
