AOZ8235
Five-line TVS Diode
General Description
The AOZ8235 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 five TVS
diodes in a single
package. Due to the flexibility of the design, the package
can be configured 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
(±15 kV air, ±8 kV contact discharge).
The AOZ8235 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.
