AOZ8211 Datasheet, PDF (1/6 Pages) Alpha & Omega Semiconductors – One-line TVS Diode

AOZ8211
One-line TVS Diode
General Description
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]² ™ technology for superior clamping
performance.
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).
The AOZ8211 comes in an RoHS compliant SOD923
package and is rated over a -40°C to +85°C ambient
temperature range.
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.
