AOZ8102
Ultra-Low Capacitance TVS Diode Array
General Description
The AOZ8102 is a transient voltage suppressor array
designed to protect high speed data lines from ESD and
lightning.
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. They may be used to meet the
ESD immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge). The TVS diodes
provide effective suppression of ESD voltages:
±20kV (air discharge) and ±20kV (contact discharge).
The AOZ8102 comes in a RoHS compliant DFN-6
1.6mm x 1.6mm package and is rated over a -40°C to
+85°C ambient temperature range. The AOZ8102 is
compatible with both lead free and SnPb assembly
techniques. The small size, low capacitance and high
ESD protection makes it ideal for protecting high speed
video and data communication interfaces.
