AOZ8204
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 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 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.
