AOZ8025
6-Line EMI Filter with Integrated ESD Protection
General Description
Features
The AOZ8025 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
AOZ8025 has been optimized for protection of color LCD
displays and CCD camera lines in cellular phones and
other portable consumer electronic devices.
z 6 lines for EMI filtering and ESD protection:
The AOZ8025 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 100Ω and a capacitance
value of 9pF are used to achieve -20dB minimum
attenuation from 1.0GHz to 3.0GHz. The TVS diodes
provide effective suppression of ESD voltages in excess
of ±20kV (contact discharge) and ±20kV (air discharge).
This exceeds IEC 61000-4-2, level 4 ESD immunity test.
– Exceeds IEC 61000-4-2, level 4 (ESD) immunity test
– ±20kV (contact discharge) and ±20kV (air discharge)
z Trench Vertical Structure [TVS]2 ™ based technology
used to achieve excellent ESD clamping and filter
performance over the full operating display range
z Filter performance: -20db attenuation from 1.0GHz to
3.0GHz
z Low operating voltage: 5.0V
z Capacitance stability over wide range of voltages and
temperatures
z DFN package: 3.0mm x1.35mm
z Pb-Free device
Applications
z EMI filtering and ESD protection for data lines
z LCD displays, camera interface, I/O interface
z Portable handheld devices, cell phones,
PDA phones
The AOZ8025 comes in an RoHS compliant,
3.0mm x 1.35mm DFN package and is rated over a
-40°C to +85°C ambient temperature range.
