AOZ8234
AOZ8234 is Four-line TVS Diode manufactured by Alpha & Omega Semiconductors.
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 k V air, ±8 k V contact discharge).
The AOZ8234 es in an Ro HS pliant DFN package and is rated over a -40 °C to +85 °C ambient temperature range.
The very small 1.45 mm x 1.0 mm x 0.55 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 high speed video and data munication interfaces.
