AOZ8831 Ultra Low Capacitance One-line Bi-directional TVS Diode General Description Features The AOZ8831 is an ultra low capacitance one-line bi-directional transient voltage suppressor diode designed to protect 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. It may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15kV air, 15kV contact discharge). The AOZ8831 comes in an RoHS compliant DFN package and is rated over a -40C to +85C ambient temperature range. The ultra-small 1.0 x 0.6 x 0.5mm DFN 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) 15kV (air), 15kV (contact) - Human Body Model (HBM) 15kV Small package saves board space Ultra low capacitance: 0.35pF 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 1 2 Bidirection Protection of Single Line Rev. 3.0 September 2013 www.aosmd.com Page 1 of 9 AOZ8831 Ordering Information Part Number Ambient Temperature Range Package Environmental AOZ8831DI-05 -40C to +85C DFN 1.0 x 0.6 Green Product AOS Green Products use reduced levels of Halogens, and are also RoHS compliant.
