The AOZ8300 is a transient voltage suppressor array
designed to protect high speed data lines from ESD and
This device incorporates eight 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. They AOZ8300 may be used to
meet the ESD immunity requirements of IEC 61000-4-2,
Level 4. The TVS diodes provide effective suppression
of ESD voltages: ±15 kV (air discharge) and ±8 kV
(contact discharge).
The AOZ8300 comes in a Halogen Free and RoHS
compliant, SOT-23 package and is rated over a
-40 °C to +85 °C ambient temperature range. Both
packages are compatible with lead free and SnPb
assembly techniques. The small size, low capacitance,
and high ESD protection makes the AOZ8300 ideal for
protecting high speed video and data communication
