Nexperia PESD2CAN
CAN bus ESD protection diode
7. Application information
The PESD2CAN is designed for the protection of two automotive CAN bus lines from the
damage caused by ESD and surge pulses. The PESD2CAN can be used for both,
high-speed CAN bus and fault-tolerant CAN bus protection. The PESD2CAN provides a
surge capability of up to 230 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 PESD2CAN as close to the input terminal or connector as possible.
2. Minimize the path length between the PESD2CAN and the protected line.
3. Keep parallel signal paths to a minimum.
4. Avoid running protection conductors in parallel with unprotected conductors.
5. Minimize all Printed-Circuit Board (PCB) conductive loop s 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.
