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 -40C to +85C 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.
