AOZ8831-05
Ultra Low Capacitance One-line
Bi-directional TVS Diode
General Description
Features
The AOZ8831-05 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.

ESD protection for high-speed data lines:
– Exceeds: IEC 61000-4-2 (ESD) ±20kV (air),
±20kV (contact)
– Human Body Model (HBM) ±15kV

Small package saves board space
This device incorporates one TVS diode in an ultra-small
DFN 1.0 x 0.6 package. It may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4.

Ultra low capacitance: 0.22pF

Low clamping voltage

Operating voltage: 5V
The AOZ8831-05 comes in an RoHS compliant DFN
package and is rated over a -40°C to +85°C ambient
temperature range.

Pb-free device
The ultra-small 1.0 x 0.6 x 0.4mm 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.
