AOZ8231A

One-line Bi-directional TVS Diode

General Description

The AOZ8231A 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 AOZ8231A 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.

Applications

Keypads, data lines, buttons

Notebook computers

Digital Cameras

Portable GPS

MP3 players

Features

Notes:

1. Dimensions and tolerancing conform to ASME Y14.5-2009.

2. All dimensions are in milliteters.

3. “e” represents the terminal grid pitch.

4. N isthe total number of terminals.

5. A visual index feature must be located within the hatched area. Typical index feature (chamfer) must be located on the edge

of the Pin#1 feature.

6. This dimension includes stand-off height “A1” and packaged body thickness, but does not include attached feature e.g. external

heatsink or chip capacitors, an internal heatslug is not considered as attached feature.

7. Dimension “A1” is primarily terminal plating, and does not include small metal protrusions.
