General Description

The AOZ8001A is a transient voltage suppressor array designed to protect high speed data lines from ESD and lightning.

This device incorporates four 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 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 up to ±30kV (air discharge) and ±30kV (contact discharge).

The AOZ8001A comes in RoHS compliant, SOT-143 package and is rated over a -40°C to +85°C ambient temperature range. It is compatible with both lead free and SnPb assembly techniques.

The very small SOT-143 package is ideal for applications where PCB space is a premium. The small size, low capacitance and high ESD protection makes it ideal for protecting high speed video and data communication interfaces.
