7. Application information

The PESDxS1UB series is designed for unidirectional protection of one single data line
from the damage caused by ESD (Electro Static Discharge) and Surge Pulses. The
PESDxS1UB series may be used on lines where the signal polarity is above or below
ground. The PESDxS1UB series provides a surge capability of up to 330 Watts per line for
a 8/20 µs waveform.

Circuit board layout and protection device placement:

Circuit board layout is critical for the suppression of ESD, EFT and Surge transients.
The following guidelines are recommended:

1. Place the protection device as close to the input terminal or connector as possible.

2. The path length between the protection device and the protected line should be
minimized.

3. Keep parallel signal paths to a minimum.

4. Avoid running protection conductors in parallel with unprotected conductor.

5. Minimize all printed-circuit board conductive loops including power and ground loops.

6. Minimize the length of the transient return path to ground.

7. Avoid using shared transient return paths to a common ground point.

8. Ground planes should be used whenever possible. For multilayer printed-circuit
boards, use ground vias.
