 Array of surge rated diodes with internal TVS diode
 Small package saves board space
 Protects four I/O lines
 Low capacitance between I/O lines: 0.25 pF
 Low clamping voltage
 Low operating voltage: 3.3V, 5.0 V
The AOZ8809 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, 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 AOZ8809 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 3.0/3.1 applications, such as Digital
TVs, DVD players, computing, set-top boxes and MDDI
applications in mobile computing devices.
The AOZ8809 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.
