General Description

The AOZ8S502BDS-03 is a 1-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 AOZ8S502BDS-03 provides a typical capacitance of

23 pF and low clamping voltage making it ideally suited

for data transmission protection in mobile and computing

devices.

The AOZ8S502BDS-03 comes in a RoHS compliant and

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

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