1.1 General description

The IP4059CX5 is designed to protect several I/O pins of computer interfaces, such as

Universal Serial Bus (USB) 2.0, USB On-The-Go (OTG), Ethernet, Digital Visual Interface

(DVI) etc. The IP4059CX5 incorporates ultra-low capacity diodes to provide protection to

downstream components from ElectroStatic Discharge (ESD) voltages as high as 8 kV

contact discharge according to the IEC 61000-4-2 model.

The device is fabricated using monolithic silicon technology and integrates four ultra-low

capacity ESD protection diodes in a 0.5 mm pitch Wafer-Level Chip-Scale Package

(WLCSP) measuring 0.96 mm by 1.34 mm only.

1.2 Features and benefits

 Pb-free, RoHS compliant and free of halogen and antimony (Dark Green compliant)

 4 ultra-low input capacity rail-to-rail ESD protection diodes with Cd = 3.0 pF

 Integrated ESD protection withstanding 8 kV contact discharge and 15 kV air

discharge

 WLCSP with 0.5 mm pitch

1.3 Applications

General purpose ElectroMagnetic Interference (EMI) and Radio Frequency Interference

(RFI) filtering and downstream ESD protection for USB ports inside:

 Cellular and Personal Communication System (PCS) mobile handsets

 PC peripherals and PCs

 Cordless telephones

 Wireless data and Local Area Network (LAN) systems

 Personal Digital Assistants (PDAs)

 Digital cameras
