Product data sheet
The PESDxS1UL series is designed for protection of one unidirectional data line from the
damage caused by ESD and surge pulses. The PESDxS1UL series may be used on lines
where the signal polarities are either positive or negative with respect to ground. The
PESDxS1UL series provides a surge capability of 150 W for an 8/20 s waveform.
Circuit board layout and protection device placement
Circuit board layout is critical for the suppression of ESD, Electrical Fast Transient (EFT)
and surge transients. The following guidelines are recommended:
1. Place the PESDxS1UL as close to the input terminal or connector as possible.
2. The path length between the PESDxS1UL and the protected line should be
3. Keep parallel signal paths to a minimum.
4. Avoid running protected conductors in parallel with unprotected conductors.
5. Minimize all Printed-Circuit Board (PCB) conductive loops including power and
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 PCBs, use ground
