AOZ8205DI
Five-line TVS Diode Array
General Description
The AOZ8205 is a transient voltage suppressor (TVS)
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 or five channel unidirectional TVA 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,
±8 kV contact discharge).
The AOZ8205 comes in an RoHS compliant
DFN 1.6 mm x 1.6 mm package and is rated over a
-40 °C to +85 °C ambient temperature range.
The very small DFN package makes the AOZ8205 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.
