10. Application 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 postitive or negative with respect to ground. THe PESD36VS2UT

provices a surge capability of 160 W per line for an 8/20 µs waveform.

Fig. 7. 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 device as close to the input terminal or connector as possible.

2. Minimize the path length between the device and the protected line.

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. Use ground planes whenever possible. For multilayer PCBs, use ground vias.

11. Test information

Quality information

This product has been qualified in accordance with the Automotive Electronics Council (AEC)
