General Description

The AOZ8904 is a transient voltage suppressor array designed to protect high speed data lines from Electro Static Discharge (ESD) and lightning. This device incorporates eight surge rated, low capacitance steering diodes and a Transient Voltage Suppressor (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 may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air,±8kV contact discharge).

The AOZ8904 comes in a Halogen Free and RoHS compliant SOT-23 and SC-70 packages. It is rated over a

-40°C to +85°C ambient temperature range.
