AOZ8204DI Datasheet, PDF (1/7 Pages) Alpha & Omega Semiconductors – Four-line TVS Diode Array

AOZ8204DI
Four-line TVS Diode Array
General Description
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 TVS diodes 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
interfaces.
