AOZ8040

AOZ8040 8-Line EMI Filter with Integrated ESD Protection General Description The AOZ8040 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 AOZ8040 has been optimized for protection of color LCD displays and CCD camera lines in cellular phones and other portable consumer electronic devices. The AOZ8040 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 ES...
