AOZ8905 Datasheet, PDF (1/10 Pages) Alpha & Omega Semiconductors – Ultra-Low Capacitance TVS Diode Array

AOZ8905
Ultra-Low Capacitance TVS Diode Array
General Description
The AOZ8905 is a transient voltage suppressor array
designed to protect high speed data lines such as HDMI,
USB 2.0, 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 AOZ8905 provides a typical line to line capacitance
of 0.35pF and low insertion loss up to 3GHz providing
greater signal integrity making it ideally suited for HDMI
1.3 or USB 2.0 applications, such as Digital TVs,
DVD players, Computing, set-top boxes and MDDI
applications in mobile computing devices.
The AOZ8905 comes in RoHS compliant and halogen
free SOT23-6L package and is rated -40°C to +85°C
junction temperature range.
