Product data sheet
1. Product profile
1.1 General description
The IP4352CX24 is a diode array designed to provide protection to downstream
components against ElectroStatic Discharge (ESD) voltages as high as 15 kV.
The IP4352CX24 integrates 9 pairs of rail-to-rail diodes, 15 resistors and 12 Zener diodes
in a single Wafer-Level Chip-Scale Package (WLCSP) using monolithic silicon
semiconductor technology.
These features make the IP4352CX24 ideal for applications requiring miniaturized
components, such as mobile phone handsets, cordless telephones and personal digital
devices.
