AOZ8831-24
Ultra Low Capacitance One-line
Bi-directional TVS Diode
General Description
Features
The AOZ8831-24 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.

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
(±15kV air, ±13kV contact discharge).
The AOZ8831-24 comes in an RoHS compliant DFN
package and is rated over a -40°C to +85°C ambient
temperature range.
ESD protection for high-speed data lines:
– Exceeds: IEC 61000-4-2 (ESD) ±15kV (air),
±13kV (contact)
– Human Body Model (HBM) ±15kV

Small package saves board space

Ultra low capacitance: 0.35pF

Low clamping voltage

Operating voltage: 24V

Pb-free device
Applications

Portable handheld devices
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.
