AOZ8510
8-Line EMI Filter with Integrated ESD Protection
General Description
Features
The AOZ8510 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
AOZ8510 has been optimized for protection of color LCD
displays and CCD camera lines in cellular phones and
other portable consumer electronic devices.
●
8 lines for EMI filtering and ESD protection:
– Exceeds IEC 61000-4-2, level 4 (ESD) immunity test
– ±24kV (air discharge) and ±18kV (contact discharge)
●
The AOZ8510 consists of eight identical circuits
comprised of TVS diodes for ESD protection, and a
inductor–capacitor network for EMI/RFI filtering providing
a cutoff frequency at 155MHz for high speed data lines.
An inductor value of 56nH and a capacitance value of
17pF are used to achieve -40dB minimum attenuation
from 800MHz to 3.0GHz. The TVS diodes provide
effective suppression of ESD voltages in excess of
±24kV (air discharge) and ±18kV (contact discharge).
This exceeds IEC 61000-4-2, level 4 ESD immunity test.
