1.1General 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.
