AOSMD AOZ8205 Five-line tvs diode array Datasheet

AOZ8205
Five-line TVS Diode Array
General Description
Features
The AOZ8205 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
(±15kV air, ±8kV contact discharge).
●
●
●
●
●
●
The AOZ8205 comes in an RoHS compliant SC-89
package and is rated over a -40°C to +85°C ambient
temperature range.
ESD protection for high-speed data lines:
– Exceeds: IEC 61000-4-2 (ESD) ±30kV (air),
±30kV (contact)
– Human Body Model (HBM) ±30kV
Trench Vertical Structure [TVS]2 ™ based technology
used to achieve excellent ESD clamping performance
Small package saves board space
Low insertion loss
Protects five unidirectional or four bidirectional I/O
lines
Low clamping voltage
Low operating voltage: 5.0V
Green product, Pb-free
Applications
●
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.

Applications Information
Device Connection for Protection of Five
Unidirectional Data Lines
These devices are designed to protect up to five
unidirectional data lines. The device is connected as
follows.
1. Unidirectional protection of five I/O lines is achieved
by connecting pins 1, 3, 4, 5 and 6 to the data lines.
Connect pin 2 to ground. 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.
