7. Application information
The device is designed for the protection of two automotive CAN bus lines from surge
pulses and ESD damage. The device is suitable on lines where the signal polarities are
both, positive and negative with respect to ground.
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.
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
suitable for use in automotive applications.
