AOZ8811
Ultra-Low Capacitance One-line TVS Diode
General Description
Features
The AOZ8811 is a ultra-low capacitance one-line
transient voltage suppressor diode designed to protect
very high-speed data lines and 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 1.0 x 0.6 package. During transient conditions, the
ultra-low capacitance one-line TVS diode directs the
transient to ground. It may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±15kV contact discharge).
 Small package saves board space
The AOZ8811 comes in an RoHS compliant DFN
package and is rated over a -40°C to +85°C ambient
temperature range.
Applications
The ultra-small DFN 1.0 x 0.6 x 0.5mm 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.
 Notebook computers

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.
