Alpha and Omega Semiconductor
General Description
The AOZ8829-03 is a transient voltage suppressor array designed to protect high speed data lines such as HDMI 1.4/2.0, USB 3.1, MDDI, SATA, and Gigabit Ethernet from damaging ESD events.
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.
The AOZ8829-03 provides a typical line-to-line capacitance of 0.25 pF and low insertion loss up to 6 GHz providing greater signal integrity making it ideally suited for HDMI 1.4/2.0 or USB 3.1 applications, such as Digital TVs, DVD players, computing, set-top boxes and MDDI applications in mobile computing devices.
The AOZ8829-03 comes in a RoHS compliant and Halogen Free 2.5 mm x 1.0 mm x 0.55 mm DFN-10 package and is rated for -40 °C to +85 °C junction temperature range.
