The AOZ8234 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 

(±15 kV air, ±8 kV contact discharge).

The AOZ8234 comes in an RoHS compliant DFN 

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

temperature range. 

The very small 1.45 mm x 1.0 mm x 0.55 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 high speed video 

ａnd data communication interfaces
