General Description

The AOZ8802A is a transient voltage suppressor array designed to protect high speed data lines such as HDMI, MDDI, USB, SATA, and Gigabit Ethernet from damaging ESD events.

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.

The AOZ8802A provides a typical line to line capacitance of 0.3pF and low insertion loss up to 6GHz providing greater signal integrity making it ideally suited for HDMI 1.3 applications, such as Digital TVs, DVD players, set-top boxes and USB applications in mobile computing devices.

The AOZ8802A comes in a RoHS compliant and Halogen Free 1.6mm x 1.0mm x 0.55mm DFN-6 package and is rated -40°C to +85°C junction temperature range.
