General Description

The AOZ8331DI-03 is a single channel bidirectional high

surge transient voltage suppressor designed to protect

data lines such as audio line and power rail from

damaging ESD or surge events.

This device incorporates two unidirectional TVS diodes in

a single package. During transient conditions, the

bidirectional diodes direct the transient to either the

positive side of the power supply line or to ground.

The AOZ8331DI-03 provides a typical line-to-line

capacitance of 75 pF and low clamping voltage making it

ideally suited for data transmission protection in mobile

and computing devices.

The AOZ8331DI-03 comes in a RoHS compliant and

Halogen Free 1.0 mm x 0.6 mm x 0.5 mm package and is

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