PESDXS4UD_SER_2
Product data sheet
The PESDxS4UD series is designed for protection of up to 4 unidirectional data lines from
the damage caused by ESD and surge pulses. The PESDxS4UD series may be used on
lines where the signal polarities are above or below ground. The PESDxS4UD series
provides a surge capability of 200 W per line 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 PESDxS4UD as close to the input terminal or connector as possible.
2. The path length between the PESDxS4UD 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
