AOZ8831DT-03
Ultra Low Capacitance One-line
Bi-directional TVS Diode
General Description
Features
The AOZ8831DT-03 is an ultra low capacitance one-line
bi-directional transient voltage suppressor diode
designed to protect high speed data lines and voltage
sensitive electronics from high transient conditions and
ESD.
– Human Body Model (HBM) ±15kV
Small package saves board space
Ultra low capacitance: 0.22pF
Low clamping voltage
Operating voltage: 3.6V
Pb-free device
Applications
The ultra-small 1.0 x 0.6mm DFN package makes it ideal
for applications where PCB space is a premium. The
small size and high ESD protection makes it ideal for protecting voltage sensitive electronics from high transient
conditions and ESD.
