AOZ8033 4-Line EMI Filter with Integrated ESD Protection The AOZ8033 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 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 AOZ8033 has been optimized for protection of color LCD displays and CCD camera lines in cellular phones and other portable consumer electronic devices. The AOZ8033 consists of four identical circuits comprised of TVS diodes for ESD protection, and a network for EMI/RFI filtering. A series resistor value of 100 and a capacitance value of 28pF are used to achieve -35dB minimum attenuation from 800MHz 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.
