Applications Information

Device Connection Options

These low capacitance TVS diodes are designed to

provide common mode protection for one high-speed

line or differential protection for one line pair. The

device is bidirectional and may be used on lines where

the signal polarity is positive and negative.

Circuit Board Layout Recommendations for Suppres-

sion 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 connec-

tors 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.
