AOZ8035 Datasheet | Alpha & Omega Semiconductors

Description The AOZ8035 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 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 AOZ8035 has been optimized for protection of color LCD displays and CCD camera lines in cellular phones and other portable consumer electronic devices. The AOZ8035 consists of six identical circuits prised 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 28p F are used to achieve -35d B minimum attenuation from 800MHz to 3.0GHz. The TVS diodes provide effective suppression of ESD voltages in excess of ±20k V (contact discharge) and ±20k V (air discharge). This exceeds IEC 61000-4-2, level 4 ESD immunity test. The AOZ8035 es in an Ro HS pliant, 2.50mm x 1.20mm DFN package and is rated over a -40°C to +85°C ambient temperature range.
