AOZ8013
4-Line EMI Filter with Integrated ESD Protection
General Description
Features
The AOZ8013 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
– ±18kV (air discharge) and ±18kV (contact discharge)

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
AOZ8013 has been optimized for protection of color LCD
displays and CCD camera lines in cellular phones and
other portable consumer electronic devices.
• Filter performance: -35db attenuation from 800MHz to
2.2GHz
• Low operating voltage: 5.0V
• Capacitance stability over wide range of voltages and
temperatures
The AOZ8013 consists of four identical circuits
comprised of TVS diodes for ESD protection, and a
resistor–capacitor network for EMI/RFI filtering.
• DFN package, 2.0 x 2.0mm
• Pb-free device
A series resistor value of 100¾ and a capacitance
value of 28pF are used to achieve -35dB minimum
attenuation from 800MHz to 2.2GHz. The TVS diodes
provide effective suppression of ESD voltages in excess
of ±18kV (air discharge) and ±18kV (contact discharge).
This exceeds IEC 61000-4-2, level 4 ESD immunity test.
• Green product
Applications
• EMI filtering and ESD protection for data lines
• LCD displays, camera interface, I/O interface
• Portable handheld devices, cell phones, PDA phones
The AOZ8013 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.
