AOZ8131
Ultra Low Capacitance One-Line
Bi-directional TVS Diode
General Description
The AOZ8131 is an ultra low capacitance one-line
bi-directional transient voltage suppressor diode
designed to protect high speed data lines and 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 IEC 61000-4-2,
Level 4 (±15kV air, ±8kV contact discharge).
The AOZ8131 comes in an RoHS compliant DFN 1006
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 tran-
sient conditions and ESD.
Features
ESD protection for high-speed data lines:
– Exceeds:
IEC 61000-4-2 (ESD) ±24kV (air), ±24kV (contact)
IEC 61000-4-4(EFT) ±40A (5/50nS)
IEC 61000-4-5 (Lightning) ±4A
– Human Body Model (HBM) ±30kV
Small package saves board space
Ultra low capacitance: 1.25pF
Low clamping voltage
Low operating voltage: 5.0V
Pb-free device
Applications

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.
