The ESDA6V1-4BC6 array is the ideal product for use as board level protection of ESD sensitive semi-

conductor components.

The tiny SOT23-6L package allows design flexibility in the design of “crowded” boards where the space

saving is at a premium. This enables to shorten the routing and can contribute to improve ESD perform-

ance.

2. Circuit Board Layout

Circuit board layout is a critical design step in the suppression of ESD induced transients. The following

guidelines are recommended :

■ The ESDA6V1-4BC6 should be placed as near as possible to the input terminals or connectors.

■ Minimise the path length between the ESD suppressor and the protected device

■ Minimise all conductive loops, including power and ground loops

■ The ESD transient return path to ground should be kept as short as possible.

■ Use ground planes whenever possible.
