AOZ8014
4-Line EMI Filter with Integrated ESD Protection
General Description
Features
The AOZ8014 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 electro-
static discharge (ESD) protection in portable electronic
equipment. This state-of-the-art device utilizes AOS
● 4 lines for EMI filtering and ESD protection:
– Exceeds IEC 61000-4-2, level 4 (ESD) immunity test
– ±17kV (air discharge) and ±17kV (contact discharge)
2
● Trench Vertical Structure [TVS] ™ based technology
2
used to achieve excellent ESD clamping & filter
performance over the full operating display range
leading edge Trench Vertical Structure [TVS] ™
technology for superior clamping performance and filter
attenuation over the full operating display range. The
AOZ8014 has been optimized for protection of color LCD
displays and CCD camera lines in cellular phones and
other portable consumer electronic devices.
● Filter performance: -25db attenuation from 800MHz to
3.0GHz
● Low operating voltage: 5.0V
● Capacitance stability over wide range of voltages and
temperatures
The AOZ8014 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 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.
● DFN package, 2.0 x 2.0 mm
● Pb-Free device
Applications
● EMI filtering and ESD protection for data lines
● LCD displays, camera interface, I/O interface
● Portable handheld devices, cell phones,
PDA phones
The AOZ8014 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.

2. Controlling dimension is millimeter, converted inch dimensions are not necessarily exact.
3. Dimension b applied 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, dimension b should not be measured in that radius area.
4. Coplanarity ddd applies to the terminals and all other bottom surface metallization.
