AOZ8821
Ultra-Low Capacitance One-line TVS Diode
General Description
Features
The AOZ8821 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 0.6 x 0.3 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 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 0.6 x 0.3mm 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
