AOZ80756-Line EMI Filter with Integrated ESD Protection General Description
The AOZ8075 is a 6-line device integrating EMI filtering with ESD protection for each line. It is designed to
suppress unwanted EMI/RFI signals and provide electro-static 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 AOZ8075 has been optimized for protection of color LCD displays and CCD camera lines in cellular phones and other portable consumer electronic devices.
The AOZ8075 consists of six identical circuits
comprised of TVS diodes for ESD protection, and a resistor–capacitor network for EMI/RFI filtering. A series resistor value of 100 Ω and a capacitance value of 8 pF are used to achieve -20 dB minimum attenuation from 700 MHz to 3.0 GHz. The TVS diodes provide effective suppression of ESD voltages in excess of ±15 kV (contact discharge) and ±15 kV (air discharge). This exceeds the IEC 61000-4-2, level 4 ESD immunity test.
The AOZ8075 comes in an RoHS compliant,
2.50 mm x 1.20 mm DFN package and is rated over a -40 °C to +85 °C ambient temperature range.
