AOZ8204
Four-line TVS Diode Array
General Description
The AOZ8204 is a transient voltage suppressor diode array designed to protect data lines from high transient conditions and ESD. 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 (15kV air, 8kV contact discharge). The AOZ8204 comes in an RoHS compliant SC-89 package and is rated over a -40C to +85C ambient temperature range. The very small 1.7 x 1.7 x 0.6mm SC-89 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 communication interfaces.
Features

Applications Information
Device Connection for Protection of Four Data Lines These devices are designed to protect up to four unidirectional data lines. The device is connected as follows. 1. Unidirectional protection of four I/O lines is achieved by connecting pins 1, 3, 4, and 6 to the data lines. Connect pin 2 to ground. The ground connection should be made directly to the ground plane for best results. The path length is kept as short as possible to reduce the effects of parasitic inductance in the board traces.

Device Connection for Protection of Two Bidirectional Data Lines These devices are designed to protect up to two bidirectional data lines. The device is connected as follows. 1. Bidirectional protection of two I/O lines is achieved by connecting pins 1 and 3 to the data lines. Connect pin 4 and 6 to ground. The ground connection should be made directly to the ground plane for best results. The path length is kept as short as possible to reduce the effects of parasitic inductance in the board traces.

Circuit Board Layout Recommendations for Suppression of ESD Good circuit board layout is critical for the suppression of ESD induced transients. The following guidelines are recommended:

Place the TVS near the input terminals or connectors to restrict transient coupling. Minimize the path length between the TVS and the protected line. Minimize all conductive loops including power and ground loops. The ESD transient return path to ground should be kept as short as possible. Never run critical signals near board edges. Use ground planes whenever possible.
