AOZ8011
8-Line EMI Filter with Integrated ESD Protection
General Description
Features
The AOZ8011 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
AOZ8011 has been optimized for protection of color LCD
displays and CCD camera lines in cellular phones and
other portable consumer electronic devices.
●
●
●
●
●
The AOZ8011 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 17pF are used to achieve -25dB minimum
attenuation from 800MHz to 3.0GHz. The TVS diodes
provide effective suppression of ESD voltages in excess
of ±17kV (air discharge) and ±17kV (contact discharge).
This exceeds IEC 61000-4-2, level 4 ESD immunity test.
8 lines for EMI filtering and ESD protection:
– Exceeds IEC 61000-4-2, level 4 (ESD) immunity test
– ±17kV (air discharge) and ±17kV (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: -25db attenuation from 800MHz to
3.0GHz
Low operating voltage: 5.0V
Capacitance stability over wide range of voltages and
temperatures

Notes:
1. Dimensions and tolerancing conform to ASME Y14.5M-1994.
2. All dimensions are in millimeters.
3. Dimension b applies to metallized terminal and is measured between 0.10mm and 0.30mm from the terminal tip. If the terminal has the
optional radius on the other end of the terminal, the dimension b should not be measured in that radius area.
4. Coplanarity ddd applies to the terminals and all other bottom surface metallization.
