Overview
4-Line EMI Filter with Integrated ESD Protection AOZ8013 General Description The AOZ8013 is an 4-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 AOZ8013 has been optimized for protection of color LCD displays and CCD camera lines in cellular phones and other portable consumer electronic devices.
The AOZ8013 consists of four identical circuits comprised of TVS diodes for ESD protection, and a resistor–capacitor network for EMI/RFI filtering.
A series resistor value of 100¾ and a capacitance value of 28pF are used to achieve -35dB minimum attenuation from 800MHz to 2.
2GHz.
The TVS diodes provide effective suppression of ESD voltages in excess of ±18kV (air discharge) and ±18kV (contact discharge).
This exceeds IEC 61000-4-2, level 4 ESD immunity test.
The AOZ8013 comes in an RoHS compliant, 2.
0mm x 2.
0mm DFN package and is rated over a -40°C to +85°C ambient temperature range.
Features • 4 lines for EMI filtering and ESD protection: – Exceeds IEC 61000-4-2, level 4 (ESD) immunity test – ±18kV (air discharge) and ±18kV (contact discharge) • Trench Vertical Structure [TVS]2 ™ based technology used to achieve excellent ESD clamping & filter performance over the full operating display range • Filter performance: -35db attenuation from 800MHz to 2.
