AOZ8811 Ultra-Low Capacitance One-line TVS Diode General Description Features 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. z 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). z Small package saves board space The AOZ8811 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 0.5mm 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. z Notebook computers Typical Application Pin Configuration – Exceeds: IEC 61000-4-2 (ESD) ±15V (air), ±15kV (contact) – Human Body Model (HBM) ±15kV z Ultra-low capacitance: 0.65pF z Low clamping voltage z Low operating voltage: 5V z Green product z Portable handheld devices z Keypads, data lines, buttons z Digital Cameras z Portable GPS z MP3 players Signal Line Cathode 1 2 Anode Unidirection Protection of Single Line Rev. 1.1 October 2010 www.aosmd.com Page 1 of 7 AOZ8811 Ordering Information Part Number Ambient Temperature Range Package Environmental AOZ8811DI-05 -40°C to +85°C DFN 1.0 x 0.6 RoHS Compliant Green Product AOS Green Products use reduced levels of Halogens, and are also RoHS compliant.
