The AOZ8204 is a transient voltage suppressor diode 

array designed to protect data lines from high transient 

conditions and ESD. This state-of-the-art device utilizes 

AOS leading edge Trench Vertical Structure [TVS]

2

™ 

technology for superior clamping performance.

This device incorporates four TVSdiodes in a single 

package. Due to the flexibility of the design, the package 

can be configured as a two channel bidirectional TVS 

array. During transient conditions, the TVS diodes direct 

the transient to ground. They may be used to meet the 

ESD immunity requirements of IEC 61000-4-2, Level 4 

(±15kV air, ±8kV contact discharge).

The AOZ8204 comes in an RoHS compliant DFN 

package and is rated over a -40°C to +85°C ambient 

temperature range. 

The very small 1.6 x 1.6mm 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 high speed video and data communication
