AOZ8170
8-Line EMI Filter with Integrated ESD Protection
General Description
Features
The AOZ8170 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
AOZ8170 has been optimized for protection of color LCD
displays and CCD camera lines in cellular phones and
other portable consumer electronic devices.
z 8 lines for EMI filtering and ESD protection:
The AOZ8170 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 8pF
are used to achieve -20dB minimum attenuation from
700MHz to 3.0GHz. The TVS diodes provide effective
suppression of ESD voltages in excess of ±15kV (air discharge) and ±15kV (contact discharge). This exceeds
IEC 61000-4-2, level 4 ESD immunity test.
