AOZ8231B
One-line Bi-directional TVS Diode
General Description
Features
The AOZ8231B is a one-line bi-directional transient
voltage suppressor diode designed to protect voltage
sensitive electronics from high transient conditions and
ESD.
 ESD protection for high-speed data lines:
This device incorporates one TVS diode in an ultra-small
DFN package. It may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge).
The AOZ8231B comes in an RoHS compliant
DFN 1.0 x 0.6 package and is rated over a -40°C to
+85°C ambient temperature range.
The ultra-small 1.0 x 0.6 x 0.5mm 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.
– Exceeds: IEC 61000-4-2 (ESD) ±18kV (air),
±18kV (contact)
– Human Body Model (HBM) ±30kV
– IEC 61000-4-5 (Lightning) ±4A (8/20µS)
– IEC 61000-4-4 (EFT) ±40A
 Small package saves board space
 Low insertion loss
 Low clamping voltage
 Operating voltage: 8V
 Pb-free device
Applications
 Portable handheld devices
 Keypads, data lines, buttons
 Notebook computers
 Digital Cameras
 Portable GPS
 MP3 players

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.
