Overview
The IP4234CZ6,125 is a single USB 2.0 ESD Protection Device manufactured by Nexperia USA Inc. This component is designed to protect input/output (I/O) USB 2.0 ports that are sensitive to capacitive loads from being damaged by electrostatic discharge (ESD). The device utilizes a π-filter structure with a small series resistor to provide necessary protection against ESD voltages greater than ±8 kV contact discharge, compliant with IEC 61000-4-2 level 4. The ESD protection is independent of the supply voltage due to the rail-to-rail diode architecture connected to a Zener diode. It is fabricated using monolithic silicon technology and integrates two ultra-low capacitance π-filter ESD protection diodes plus a Zener diode in a miniature 6-lead SOT457 package.
