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.
