AOZ8001A
Ultra-Low Capacitance TVS Diode Array
General Description
The AOZ8001A is a transient voltage suppressor array
designed to protect high speed data lines from ESD and
lightning.
This device incorporates four 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. They may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4.
The TVS diodes provide effective suppression of ESD
voltages up to ±30kV (air discharge) and ±30kV (contact
discharge).
The AOZ8001A comes in RoHS compliant, SOT-143
package and is rated over a -40°C to +85°C ambient
temperature range. It is compatible with both lead free
and SnPb assembly techniques.
The very small SOT-143 package is ideal for applications
where PCB space is a premium. The small size, low
capacitance and high ESD protection makes it ideal for
protecting high speed video and data communication
interfaces.
