AOZ8211 One-line TVS Diode General Description Features The AOZ8211 is a one-line transient voltage suppressor diode designed to protect voltage sensitive electronics from high transient conditions and ESD. ● This device incorporates one TVS diode in an ultra-small SOD923 package. During transient conditions, the 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, ±8kV contact discharge). The AOZ8211 comes in an RoHS compliant SOD923 package and is rated over a -40°C to +85°C ambient temperature range. The ultra-small 1.0 x 0.6 x 0.4mm SOD923 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. Typical Application ESD protection for high-speed data lines: – Exceeds: IEC 61000-4-2 (ESD) ±28kV (air), ±28kV (contact) – Human Body Model (HBM) ±30kV ● Small package saves board space ● Low insertion loss ● Low clamping voltage ● Low operating voltage: 5V and 12V Applications ● Portable handheld devices ● Keypads, data lines, buttons ● Notebook computers ● Digital Cameras ● Portable GPS ● MP3 players Pin Configuration Signal Line Cathode 1 2 Anode Unidirection Protection of Single Line Rev. 2.5 January 2009 www.aosmd.com Page 1 of 6 AOZ8211 Ordering Information Part Number Ambient Temperature Range Package Environmental AOZ8211NI-05L -40°C to +85°C SOD923 RoHS Compliant Green Product AOZ8211NI-12L All AOS products are offered in packages with Pb-free plating and compliant to RoHS standards.
