General Description

The AOZ8S321UD4-03 is a transient voltage suppressor

array designed to protect high speed data lines such as

HDMI 1.4/2.0, USB 3.0/3.1, LVDS, and V-by-one from

damaging ESD events.

This device incorporates a numbers of surge rated, low

capacitance steering diodes and a TVS in a single package.

During transient conditions, the steering diodes direct the

transient to either the positive side of the power supply line

or to ground.

The AOZ8S321UD4-03 provides a typical line-to-line

capacitance of 0.15 pF and low insertion loss providing

greater signal integrity making it ideally suited for HDMI

1.4/2.0 or USB 3.0/3.1 applications, such as Digital TVs, DVD

players, computing, set-top boxes and MDDI applications in

mobile computing devices.

The AOZ8S321UD4-03 comes in a RoHS compliant and

Halogen Free 2.5 mm x 1.0 mm x 0.55 mm DFN-10 package

and is rated for -40°C to +125°C junction temperature range.
