General Description

The AOZ8205 is a transient voltage suppressor (TVS) 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 five TVS diodes in a single package. Due to the flexibility of the design, the package can be configured as a four channel bidirectional TVS array or five channel unidirectional TVA 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 (± 15kV air, ±8 kV contact discharge).

The AOZ8205 comes in an RoHS compliant DFN 1.6 mm x 1.6 mm package and is rated over a -40 °C to +85 °C ambient temperature range.

The very small DFN package makes the AOZ8205 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 communication interfaces.
