AOZ8206 Six-line TVS Diode Array  General Description
AOZ8206
Six-line TVS Diode Array
General Description
Features
The AOZ8206 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 six TVS diodes in a single
package. 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 AOZ8206 is RoHS compliant. The DFN-6 package
is rated over a -40°C to +85°C ambient temperature
range.

Applications
The very small DFN-6 1.6 x 1.6 x 0.55mm 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.

Applications Information
Device Connection for Protection of Six
Unidirectional Data Lines
I/O1
I/O2
I/O3
These devices are designed to protect up to six
unidirectional data lines. The device is connected as
follows.
1
1. Unidirectional protection of six I/O lines is achieved
by connecting pins 1, 2, 3, 4, 5 and 6 to the data
lines. The ground connection should be made
directly to the ground plane for best results. The path
length is kept as short as possible to reduce the
effects of parasitic inductance in the board traces.

Circuit Board Layout Recommendations for
Suppression of ESD
Good circuit board layout is critical for the suppression of
ESD induced transients. The following guidelines are
recommended:
●
Place the TVS near the input terminals or connectors
to restrict transient coupling.
●
Minimize the path length between the TVS and the
protected line.
●
Minimize all conductive loops including power and
ground loops.
●
The ESD transient return path to ground should be
kept as short as possible.
●
Never run critical signals near board edges.
●
Use ground planes whenever possible.
