General Description

The AOZ8S502BS2-03 is a 2-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 Bidirectional 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 AOZ8S502BS2-03 provides a typical capacitance of

22 pF and low clamping voltage making it ideally suited

for data transmission protection in mobile and computing

devices.

The AOZ8S502BS2-03 comes in a RoHS compliant and

Halogen Free SOT23-3L package and is rated for -40 °C to

+125 °C junction temperature range.
