1. Product profile
1.1 General description
The IP4359CX4 is a dual channel low capacitance ElectroStatic Discharge (ESD)
protection device, providing protection to downstream components from ESD voltages as
high as ±15 kV contact discharge and > ±15 kV air discharge according the
IEC 61000-4-2 model, far exceeding standard level 4.
The device is optimized for protection of high speed interfaces such as Universal Serial
Bus (USB) 2.0, High Definition Multimedia Interface (HDMI), Digital Visual Interface (DVI)
and other interfaces requiring very low capacitance ESD protection.
The device is available in two different heights. 0.61 mm and reduced maximum height of
0.5 mm. Both versions contain identical circuits and show an identical electrical
performance. Both ESD protection channels share common ground connections, but are
electrically separated, thereby preventing current back drive into the adjacent channel.
IP4359CX4 is fabricated using monolithic silicon technology in a single Wafer-Level
Chip-Scale Package (WLCSP). These features make the IP4359CX4 ideal for use in
applications requiring component miniaturization such as mobile phone handsets and
other portable electronic devices.
