General Description The AOZ8234 is a transient voltage suppressor diode array designed to protect data lines from high transient conditions and ESD. This state-of-the-art device utilizes AOS leading edge Trench Vertical Structure [TVS]2 ™ technology for superior clamping performance. This device incorporates four TVS diodes in a single package. Due to the flexibility of the design, the package can be configured as a two channel bidirectional TVS array. During transient conditions, the TVS diodes direct the transient to ground. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15 kV air, ±8 kV contact discharge). Features • ESD protection for high-speed data lines: – Exceeds: IEC 61000-4-2 (ESD) ±18 kV (air), ±18 kV (contact) – Human Body Model (HBM) ±30 kV • Trench Vertical Structure [TVS]2 ™ based technology used to achieve excellent ESD clamping performance • Small package saves board space • Low insertion loss • Protects four unidirectional or two bidirectional I/O lines • Low clamping voltage • Low operating voltage: 5.0V • Green product, Pb-free Applications • Portable handheld devices • Keypads, data lines • Notebook computers • Digital cameras • Portable GPS • MP3 players
