AOZ8831DT-24

AOZ8831DT-24 Ultra Low Capacitance One-line Bi-directional TVS Diode General Description Features The AOZ8831DT-24 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, ±13kV contact discharge). The AOZ8831DT-24 comes in an RoHS compliant DFN package and is rated over a -40°C to +85°C ambient temperature range. ESD protection for high-speed data lines: – Exceeds: IEC 61000-4-2 (ESD) ±15kV (air), ±13kV (contact) – Human Body Model (HBM) ±15kV  Small package saves board space  Ultra low capacitance: 0.35pF  Low clamping voltage  Operating voltage: 24V  Pb-free device Applications  Portable handheld devices The ultra-small 1.0 x 0.6mm 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.  Notebook computers  Digital Cameras  Portable GPS Typical Application Pin Configuration Signal Line 1 2 Bidirection Protection of Single Line Rev. 4.0 April 2021 www.aosmd.com Page 1 of 5 AOZ8831DT-24 Ordering Information Part Number Ambient Temperature Range Package Environmental AOZ8831DT-24 -40°C to +85°C DFN 1.0 x 0.6 Green Product AOS Green Products use reduced levels of Halogens, and are also RoHS compliant.
