AOZ8231 One-line Bi-directional TVS Diode General Description Features The AOZ8231 is a one-line bi-directional 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. It may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). The AOZ8231 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) ±24kV (air), ±24kV (contact) – Human Body Model (HBM) ±30kV – IEC 61000-4-5 (Lightning) ±5A (8/20µS) – IEC 61000-4-4 (EFT) ±40A ● Small package saves board space ● Low insertion loss ● Low clamping voltage ● Low operating voltage: 5.0V ● Pb-free device Applications ● Portable handheld devices ● Keypads, data lines, buttons ● Notebook computers ● Digital Cameras ● Portable GPS ● MP3 players Pin Configuration Signal Line Bidirection Protection of Single Line Rev. 1.9 October 2008 www.aosmd.com Page 1 of 6 AOZ8231 Ordering Information Part Number Ambient Temperature Range Package Environmental AOZ8231NI-05L -40°C to +85°C SOD923 RoHS Compliant Green Product • All AOS products are offered in packages with Pb-free plating and compliant to RoHS standards. • Parts marked as Green Products (with “L” suffix) use reduced levels of Halogens, and are also RoHS compliant.
