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. z – Exceeds IEC 61000-4-2, level 4 (ESD) immunity test – ±20kV (air discharge) and ±20kV (contact discharge) z Trench Vertical Structure [TVS]2 ™ based technology z z z z z used to achieve excellent ESD clamping & filter performance over the full operating display range Filter performance: -20db attenuation from 1.0GHz to 3.0GHz Low operating voltage: 5.0V Capacitance stability over wide range of voltages and temperatures TDFN package: 1.6mm x 4.0mm Pb-Free device Green product Applications z EMI filtering and ESD protection for data lines z LCD displays, camera interface, I/O interface z Portable handheld devices, cell phones, PDA phones The AOZ8020 comes in an RoHS compliant, 1.6mm x 4.0mm TDFN package and is rated over a -40°C to +85°C ambient temperature range.
