AOZ8001DI
Ultra-Low Capacitance TVS Diode Array
General Description
The AOZ8001DI 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: ±15kV (air discharge) and ±8kV (contact
discharge).
The AOZ8001DI comes in a RoHS compliant DFN
1.6mm x 1.6mm 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 1.6mm x 1.6mm DFN package makes it
ideal for applications where PCB space is a premium.
The DFN has a flow through package design for an
optimal and user friendly PCB layout design. The small
size, low capacitance and high ESD protection makes
it ideal for protecting high speed video and data
communication interfaces.
