AOZ8011
8-Line EMI Filter with Integrated ESD Protection
General Description
The AOZ8011 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 TM technology for superior clamping performance and filter attenuation over the full operating display range. The AOZ8011 has been optimized for protection of color LCD displays and CCD camera lines in cellular phones and other portable consumer electronic devices. The AOZ8011 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 100 and a capacitance value of 17pF are used to achieve -25dB minimum attenuation from 800MHz to 3.0GHz. The TVS diodes provide effective suppression of ESD voltages in excess of 17kV (air discharge) and 17kV (contact discharge). This exceeds IEC 61000-4-2, level 4 ESD immunity test. The AOZ8011 comes in an RoHS compliant, 1.6mm x 4.0mm DFN package and is rated over a -40C to +85C ambient temperature range.
Features
8 lines for EMI filtering and ESD protection: - Exceeds IEC 61000-4-2, level 4 (ESD) immunity test - 17kV (air discharge) and 17kV (contact discharge) Trench Vertical Structure [TVS]2 TM based technology used to achieve excellent ESD clamping & filter performance over the full operating display range Filter performance: -25db attenuation from 800MHz to 3.0GHz Low operating voltage: 5.0V Capacitance stability over wide range of voltages and temperatures DFN package 1.6 x 4.0 mm Pb-Free device

Applications
