AOSMD AOZ8533

AOZ8533
4-Line EMI Filter with Integrated ESD Protection
General Description
Features
The AOZ8533 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 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
AOZ8533 has been optimized for protection of color LCD
displays and CCD camera lines in cellular phones and
other portable consumer electronic devices.
●
4 lines for EMI filtering and ESD protection:
– Exceeds IEC 61000-4-2, level 4 (ESD) immunity test
– ±30kV (air discharge) and ±24kV (contact discharge)
●
Trench Vertical Structure [TVS]2 ™ based technology
used to achieve excellent ESD clamping & filter
performance over the full operating display range
●
Cutoff frequency: 450MHz
●
Filter performance:
The AOZ8533 consists of four identical circuits
comprised of TVS diodes for ESD protection, and a
inductor–capacitor network for EMI/RFI filtering providing
a cutoff frequency at 450MHz for high speed data lines.
An inductor value of 17nH and a capacitance value of
16pF are used to achieve greater than -30dB attenuation
at 1.0GHz. The TVS diodes provide effective suppression of ESD voltages in excess of ±30kV (air discharge)
and ±24kV (contact discharge). This exceeds IEC 610004-2, level 4 ESD immunity test.
●
– -30dB attenuation at 1.0GHz
– -25dB attenuation from 800MHz to 5.0GHz
Low operating voltage: 5.0V
The AOZ8533 comes in an RoHS compliant, 1.2mm x
1.8mm, 0.4mm pitch DFN package and is rated over a
-40°C to +85°C ambient temperature range.
●
Capacitance stability over wide range of voltages and
temperatures
●
DFN package: 1.2mm x 1.8mm, 0.4mm pitch
