AOZ8822
Ultra-Low Capacitance Two-line TVS Diode
General Description
Features
The AOZ8822 is an ultra-low capacitance two-line
transient voltage suppressor diode designed to protect
very high-speed data lines and voltage sensitive
electronics from high transient conditions and ESD.
 ESD protection for high-speed data lines:
This device incorporates two TVS diodes in an
ultra-small DFN 1.0 x 0.6 package. During transient
conditions, the ultra-low capacitance TVS diodes directs
the transient to ground. The AOZ8822 may be used to
meet the ESD immunity requirements of IEC 61000-4-2,
Level 4 (± 15 kV air, ± 15 kV contact discharge).
 Ultra-low capacitance: 0.55 pF
The AOZ8822 comes in an RoHS compliant 3-lead
DFN package and is rated over a -40 °C to +85 °C
ambient temperature range.
 Portable handheld devices
The ultra-small 1.0 mm x 0.6 mm x 0.5 mm DFN package
makes it ideal for applications where PCB space is a
premium. The small size and high ESD protection makes
it ideal for protecting voltage sensitive electronics from
high transient conditions and ESD.
 Digital Cameras
