General Description

The AOZ8231ADI 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

DFN 1006 package. It may be used to meet the ESD

immunity requirements of EC 61000-4-2, Level 4

(±15kV air, ±8kV contact discharge).

The AOZ8231ADI comes in a RoHS compliant, Halogen-

Free DFN 1.0 mm x 0.6 mm package and is rated over a

-40 °C to +85 °C ambient temperature range.

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.
