AOZ8821-03 Ultra-Low Capacitance One-line TVS Diode  General Description
AOZ8821-03
Ultra-Low Capacitance One-line TVS Diode
General Description
Features
The AOZ8821-03 is a ultra-low capacitance one-line
transient voltage suppressor diode designed to protect
very high-speed data lines and voltage sensitive
electronics from high transient conditions and ESD.
 ESD protection for high-speed data lines:
This device incorporates one TVS diode in an ultra-small
DFN 1.0 x 0.6 package. During transient conditions, the
ultra-low capacitance one-line TVS diode directs the
transient to ground. It may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±15kV contact discharge).
 Small package saves board space
The AOZ8821-03 comes in an RoHS compliant DFN
package and is rated over a -40°C to +85°C ambient
temperature range.
Applications
The ultra-small DFN 1.0 x 0.6 x 0.4mm 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.
 Notebook computers
