AOZ8231NI-05L

One-line Bi-directional TVS Diode AOZ8231 General Description 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. Features ● 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 Typical Application 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 AOZ8231NI-05L Ambient Temperature Range -40°C to +85°C Package SOD923 Environmental 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.
