Rev. 01 — 5 February 2010

Product data sheet

1. Product pro?le

1.1 General description

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 × 2.11 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.
