Product data sheet
8.1 Quality information
The PESD36VS2UT is designed for the protection of up to two unidirectional data or
signal lines from the damage caused by ESD and surge pulses. The devices may be used
on lines where the signal polarities are either positive or negative with respect to ground.
The PESD36VS2UT provides a surge capability of 160 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:
This product has been qualified in accordance with the Automotive Electronics Council
(AEC) standard Q101 - Stress test qualification for discrete semiconductors , and is
suitable for use in automotive applications.
1. Place the device as close to the input terminal or connector as possible.
2. The path length between the device 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
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
