One-line Bi-directional TVS Diode
AOZ8231
General Description
The AOZ8231 is a one-line bi-directional transient
voltage suppressor diode designed to protect voltage
sensitive electronics from high transient conditions and
ESD.
This device incorporates one TVS diode in an ultra-small
SOD923 package. It may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge).
The AOZ8231 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.
