AOZ8208
Eight-line TVS Diode Array
General Description
The AOZ8208 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 eight 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 AOZ8208 is RoHS compliant. The DFN-8 package
is rated over a -40°C to +85°C ambient temperature
range.
The very small DFN-8 1.8 x 1.2 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.
