AOZ8205
Five-line TVS Diode Array
General Description
The AOZ8205 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 â¢
technology for superior clamping performance.
This device incorporates ï¬ve TVS diodes in a single
package. Due to the ï¬exibility of the design, the package
can be conï¬gured as a four 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 AOZ8205 comes in an RoHS compliant SC-89
package and is rated over a -40°C to +85°C ambient
temperature range.
The very small 1.7 x 1.7 x 0.6mm SC-89 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.
