Rev. 02 — 3 May 2010

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.
