4-Channel Ultra-Low Capacitance TVS Diode Array
ALPHA & OMEGA SEMICONDUCTOR AOZ8S321UD4-05 4-Channel Ultra-Low Capacitance TVS Diode Array General Description
The AOZ8S321UD4-05 is a transient voltage suppressor
array designed to protect high speed data lines such as
HDMI 1.4/2.0, USB 3.0/3.1, LVDS, and V-by-one from
damaging ESD events.
This device incorporates a numbers of 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 AOZ8S321UD4-05 provides a typical line-to-line
capacitance of 0.15 pF and low insertion loss providing
greater signal integrity making it ideally suited for HDMI
1.4/2.0 or USB 3.0/3.1 applications, such as Digital TVs, DVD
players, computing, set-top boxes and MDDI applications in
mobile computing devices. Features
