AOZ8925
Ultra-Low Capacitance TVS Diode Array
General Description
Features
The AOZ8925 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 AOZ8925 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) ±30kV
 Array of surge rated diodes with internal TVS diode
 Protects four I/O lines
 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

Notes:
3. The working peak reverse voltage, VRWM, should be equal to or greater than the DC or continuous peak operating voltage level.
4. VBR is measured at the pulse test current IT.
5. Measurements performed using a 100ns Transmission Line Pulse (TLP) system.
6. The parameters are guaranteed by design and characterization.

Notes:
1. Package body sizes exclude mold flash and gate burrs. Mold flash at the non-lead sides should be less than 5 mils each.
2. Dimension “L” is measured in gauge plane.
3. Tolerance ±0.100mm (4 mil) unless otherwise specified.
4. Followed from JEDEC MO-178C & MO-193C.
6. Controlling dimension is millimeter. Converted inch dimensions are not necessarily exact.
