AOZ8900
Ultra-Low Capacitance TVS Diode Array
General Description
The AOZ8900 is a transient voltage suppressor array
designed to protect high speed data lines from Electro
Static Discharge (ESD) and lightning.
This device incorporates eight surge rated, low
capacitance steering diodes and a Transient Voltage
Suppressor (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. They may be used to meet the ESD immunity
requirements of IEC 61000-4-2, Level 4 (±15kV air,
±8kV contact discharge).
The AOZ8900 comes in RoHS compliant SOT-23
package. It is rated over a -40°C to +85°C ambient
temperature range.
Features
● ESD protection for high-speed data lines:
– Exceeds: IEC 61000-4-2 (ESD) ±15kV (air),
±8kV (contact)
– IEC 61000-4-5 (Lightning) 5A (8/20µs)
– Human Body Model (HBM) ±15kV
● Small package saves board space
● Low insertion loss
● Protects four I/O lines
● Low clamping voltage
● Low operating voltage: 5.0V
Applications
● USB 2.0 Power and Data Line Protection
● Video Graphics Cards
● Monitors and Flat Panel Displays
● Digital Video Interface (DVI)

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.
