Nexperia PESD1CAN
CAN bus ESD protection diode
7. Application information
The PESD1CAN is designed for the protection of two automotive CAN bus lines from the
damage caused by ESD and surge pulses. The device can be used for both, high-speed
CAN bus and fault-tolerant CAN bus protection. The PESD1CAN provides a surge
capability of up to 200 W per line for an 8/20 µs 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 PESD1CAN as close to the input terminal or connector as possible.
2. The path length between the PESD1CAN and the protected line should be minimized.
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 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.
