AOZ8000
Ultra-Low Capacitance TVS Diode Array
General Description
The AOZ8000 is a transient voltage suppressor array
designed to protect high speed data lines from ESD and
lightning.
This device incorporates eight surge rated, low capaci-
tance 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 AOZ8000 comes in SOT-23, DFN-6, and SC-70
packages. They are compatible with both lead free and
SnPb assembly techniques. The small size, low capaci-
tance and high ESD protection makes it ideal for protect-
ing high speed video and data communication interfaces.
