AOZ8906 Ultra-Low Capacitance TVS Diode Array  General Description
AOZ8906
Ultra-Low Capacitance TVS Diode Array
General Description
Features
The AOZ8906 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.
 ESD protection for high-speed data lines:
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 AOZ8906 provides a typical line to line capacitance
of 0.35pF 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 AOZ8906 comes in RoHS compliant and halogen
free SOT23-6L package and is rated -40°C to +85°C
junction temperature range.
– IEC 61000-4-2, level 4 (ESD) immunity test
– ±30kV (air discharge) and ±30kV (contact discharge)
– IEC61000-4-4 (EFT) 40A (5/50nS)
– IEC61000-4-5 (Lightning) 4A (8/20µS)
– Human Body Model (HBM) ±15kV
 Array of surge rated diodes with internal TVS diode
 Protects four I/O lines
 Low capacitance between I/O lines: 0.35pF
 Low clamping voltage
 Low operating voltage: 5.0V
Applications
 HDMI, USB 2.0, MDDI, SATA ports
 Monitors and flat panel displays
 Set-top box
 Video graphics cards
 Digital Video Interface (DVI)
 Notebook computers
