Datasheet
1. Product profile
1.1 General description
1.2 Features
1.3 Applications
The IP4350CX24 is a diode array designed to provide protection to downstream
components against ElectroStatic Discharge (ESD) voltages as high as 15 kV.
The IP4350CX24 integrates 9 pairs of rail-to-rail diodes, 12 Zener diodes and 15 resistors
in a single wafer-level chip-scale package. It is fabricated using monolithic silicon
semiconductor technology and measures only 1.95 mm
These features make the IP4350CX24 ideal for use in applications requiring a high degree
of miniaturization, such as mobile phone handsets, cordless telephones and personal
digital devices.
