IP4234CZ6数据手册电路保护的TVS-二极管规格书PDF

描述 Description

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 ultra-low capacitance π-filter ESD protection diodes plus a Zener diode in a miniature 6-lead SOT457 package.
