AOZ8211
One-line TVS Diode
General Description
Features
The AOZ8211 is a one-line transient voltage suppressor
diode designed to protect voltage sensitive electronics
from high transient conditions and ESD. This state-of-
the-art device utilizes AOS leading edge Trench Vertical
Structure [TVS] ™ technology for superior clamping
performance.
● ESD protection for high-speed data lines:
– Exceeds: IEC 61000-4-2 (ESD) ±28kV (air),
±28kV (contact)
– Human Body Model (HBM) ±30kV

● Trench Vertical Structure [TVS] ™ based technology
used to achieve excellent ESD clamping performance
● Small package saves board space
● Low insertion loss
This device incorporates one TVS diode in an ultra-small
SOD923 package. During transient conditions, the
one-line TVS diode directs the transient to ground. It may
be used to meet the ESD immunity requirements of IEC
61000-4-2, Level 4 (±15kV air, ±8kV contact discharge).
● Low clamping voltage
● Low operating voltage
● Green product
The AOZ8211 comes in an RoHS compliant SOD923
package and is rated over a -40°C to +85°C ambient
temperature range.
Applications
● Portable handheld devices
● Keypads, data lines, buttons
● Notebook computers
● Digital Cameras
The ultra-small 1.0 x 0.6 x 0.4mm SOD923 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.
● Portable GPS
● MP3 players
