7. Application information
The PESD15VS1ULD is designed for the protection of one unidirectional data or signal
line from the damage caused by ESD and surge pulses. The device may be used on lines
where the signal polarities are either positive or negative with respect to ground. The
PESD15VS1ULD provides a surge capability of 150 W per line for an 8/20 μs waveform.

Application diagram
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 PESD15VS1ULD as close to the input terminal or connector as possible.
2. The path length between the PESD15VS1ULD and the protected line should be
minimized.
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
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 PCBs, use ground
vias.
8. Test information
8.1 Quality information
This product has been qualified in accordance with the Automotive Electronics Council
(AEC) standard Q101 - Stress test qualification for discrete semiconductors, and is
