General Description

The AOZ8043 is an 4-line device integrating EMI filtering

with ESD protection for each line. It is designed to

suppress unwanted EMI/RFI signals and provide electro-

static discharge (ESD) protection in portable electronic

equipment. This state-of-the-art device utilizes AOS

leading edge Trench Vertical Structure [TVS]

technology for superior clamping performance and filter

attenuation over the full operating display range. The

AOZ8043 has been optimized for protection of color LCD

displays and CCD camera lines in cellular phones and

other portable consumer electronic devices.

The AOZ8043 consists of four identical circuits

comprised of TVS diodes for ESD protection, and a

resistor–capacitor network for EMI/RFI filtering.

A series resistor value of 100

value of 9pF are used to achieve -20dB minimum

attenuation from 1.0GHz to 3.0GHz. The TVS diodes

provide effective suppression of ESD voltages in excess

of ±20kV (air discharge) and ±20kV (contact discharge).

This exceeds IEC 61000-4-2, level 4 ESD immunity test.

The AOZ8043 comes in an RoHS compliant, 1.2mm x

1.8mm, 0.4mm pitch DFN package and is rated over a

-40°C to +85°C ambient temperature range.
