1、 AOZ8811Ultra-Low Capacitance One-line TVS DiodeGeneral DescriptionThe AOZ8811 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.This device incorporates one T
2、VS 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).The AOZ8811 comes in an RoHS
3、compliant DFN package and is rated over a -40C to +85C ambient temperature range. The ultra-small DFN 1.0 x 0.6 x 0.5mm 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 t
