IP4234CZ6,125

The IP4234CZ6 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 π- filter structure is implemented with a small series resistor to provide the necessary protection to signal and supply components from ESD voltages greater than ±8 KV contact discharge according IEC 61000-4-2, level 4. The ESD protection is independent of the supply voltage due to the rail-to-rail diode architecture being connected to a Zener diode. The IP4234CZ6 is fabricated using monolithic silicon technology and integrates two ultralow capacitance π-filter ESD protection diodes plus a Zener diode in a miniature 6-lead SOT457 package.
