AOSMD AOZ8020

AOZ8020
8-Line EMI Filter with Integrated ESD Protection
General Description
Features
The AOZ8020 is an 8-line device integrating EMI filtering
with ESD protection for each line. It is designed to
suppress unwanted EMI/RFI signals and provide
electrostatic discharge (ESD) protection in portable
electronic equipment. This state-of-the-art device utilizes
AOS leading edge Trench Vertical Structure [TVS]2 ™
technology for superior clamping performance and filter
attenuation over the full operating display range. The
AOZ8020 has been optimized for protection of color LCD
displays and CCD camera lines in cellular phones and
other portable consumer electronic devices.
z 8 lines for EMI filtering and ESD protection:
The AOZ8020 consists of eight identical circuits
comprised of TVS diodes for ESD protection, and a
resistor–capacitor network for EMI/RFI filtering.
A series resistor value of 100Ω and a capacitance
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.
