AOZ8806 Datasheet, PDF (1/8 Pages) Alpha & Omega Semiconductors – Ultra-Low Capacitance TVS Diode

AOZ8806
Ultra-Low Capacitance TVS Diode
General Description
The AOZ8806 is a transient voltage suppressor array
designed to protect high speed data lines such as HDMI,
USB 3.0, MDDI, SATA, and Gigabit Ethernet from
damaging ESD events.
This device incorporates twelve 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 AOZ8806 provides a typical line-to-line capacitance
of 0.3 pF and low insertion loss up to 6 GHz providing
greater signal integrity making it ideally suited for
HDMI 1.3, Thunderbolt, or USB 3.0 applications, such as
Digital TVs,
DVD players, computing, set-top boxes and MDDI
applications in mobile computing devices.
The AOZ8806 comes in a RoHS compliant and
Halogen free 3.3 mm x 1.3 mm x 0.4 mm 8-lead package
and is rated for -40 °C to +85 °C junction temperature
range.
