rev. 1.1 october 2010 www.aosmd.com page 1 of 7 AOZ8811 ultra-low capacitance one-line tvs diode general description the 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 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). the AOZ8811 comes in an rohs 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 transient conditions and esd. features z esd protection for high-speed data lines: ? exceeds: iec 61000-4-2 (esd) 15v (air), 15kv (contact) ? human body model (hbm) 15kv z small package saves board space z ultra-low capacitance: 0.65pf z low clamping voltage z low operating voltage: 5v z green product applications z portable handheld devices z keypads, data lines, buttons z notebook computers z digital cameras z portable gps z mp3 players typical application pin configuration signal line cathode 1 2 anode unidirection protection of single line
