AOZ8231A One-line Bi-directional TVS Diode General Description Features The AOZ8231A is a one-line bi-directional transient voltage suppressor diode designed to protect voltage sensitive electronics from high transient conditions and ESD. ESD protection for high-speed data lines This device incorporates one TVS diode in an ultra-small DFN 1006 package. It may be used to meet the ESD immunity requirements of EC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). The AOZ8231A comes in an RoHS compliant DFN 1.0 mm x 0.6 mm package and is rated over a -40 °C to +85 °C ambient temperature range. The ultra-small 1.0 mm x 0.6 mm x 0.5 mm 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. Applications Portable handheld devices Keypads, data lines, buttons Notebook computers Digital Cameras Portable GPS MP3 players AOZ8231ADI-02: – Exceeds: IEC 61000-4-2 (ESD) ± 30 kV (air), ± 30 kV (contact) – Human Body Model (HBM) ± 30 kV – IEC 61000-4-5 (Lightning) 6 A (8/20 μS) – IEC 61000-4-4 (EFT) 40 A AOZ8231ADI-03: – Exceeds: IEC 61000-4-2 (ESD) ± 30 kV (air), ± 30 kV (contact) – Human Body Model (HBM) ± 30 kV – IEC 61000-4-5 (Lightning) 6 A (8/20 μS) – IEC 61000-4-4 (EFT) 40 A AOZ8231ADI-05: – Exceeds: IEC 61000-4-2 (ESD) ± 30 kV (air), ±30 kV (contact) – Human Body Model (HBM) ± 30 kV – IEC 61000-4-5 (Lightning) 5 A (8/20 µS) – IEC 61000-4-4 (EFT) 40 A AOZ8231ADI-08: – Exceeds: IEC 61000-4-2 (ESD) ± 30 kV (air), ± 30 kV (contact) – Human Body Model (HBM) ± 30 kV – IEC 61000-4-5 (Lightning) 5 A (8/20 µS) – IEC 61000-4-4 (EFT) 40 A AOZ8231ADI-12: – Exceeds: IEC 61000-4-2 (ESD) ± 30 kV (air), ± 30 kV (contact) – Human Body Model (HBM) ± 30 kV – IEC 61000-4-5 (Lightning) 4 A (8/20 µS) – IEC 61000-4-4 (EFT) 40 A AOZ8231ADI-24: – Exceeds: IEC 61000-4-2 (ESD) ± 18 kV (air), ± 15 kV (contact) – Human Body Model (HBM) ± 15 kV – IEC 61000-4-5 (Lightning) 2.5 A (8/20 µS) – IEC 61000-4-4 (EFT) 40 A Small package saves board space Low insertion loss Low clamping voltage Low operating voltage Pb-free device Rev. 1.3 November 2012 www.aosmd.com Page 1 of 7 AOZ8231A Typical Application Pin Configuration Signal Line Bidirection Protection of Single Line Ordering Information Part Number Ambient Temperature Range Package Environmental -40 °C to +85 °C DFN 1.0 x 0.6 Green Product AOZ8231ADI-02 AOZ8231ADI-03 AOZ8231ADI-05 AOZ8231ADI-08 AOZ8231ADI-12 AOZ8231ADI-24 AOS Green Products use reduced levels of Halogens, and are also RoHS compliant.
