AOZ8251 One-line Bidirectional TVS Diode General Description Features The AOZ8251 is a one-line bidirectional transient voltage suppressor diode designed to protect high speed data lines and voltage sensitive electronics from high transient conditions and ESD. ESD protection for high-speed data lines: This device incorporates one bidirectional TVS diode in an ultra-small 0201 footprint package. It may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15 kV air, ±15 kV contact discharge). Small package saves board space The AOZ8251 comes in an RoHS compliant package and is rated over a -40 °C to +85 °C ambient temperature range. Pb-free device The ultra-small 0.6mm x 0.3 mm x 0.3 mm 0201 footprint package makes the AOZ8251 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.
