AOSMD AOZ8831

AOZ8831
Ultra Low Capacitance One-line
Bi-directional TVS Diode
General Description
Features
The AOZ8831 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 1006 package. It may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge).
The AOZ8831 comes in an RoHS compliant DFN 1006
package and is rated over a -40°C to +85°C ambient
temperature range.
The ultra-small 1.0 x 0.6 x 0.5mm 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.
Typical Application
ESD protection for high-speed data lines:
– Exceeds: IEC 61000-4-2 (ESD) ±15kV (air),
±8kV (contact)
– Human Body Model (HBM) ±15kV
●
Small package saves board space
●
Ultra low capacitance: 0.35pF
●
Low clamping voltage
●
Low operating voltage: 5.0V
●
Pb-free device
Applications
●
Portable handheld devices
●
Keypads, data lines, buttons
●
Notebook computers
●
Digital Cameras
●
Portable GPS
●
MP3 players
