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.
