Rev. 01 -- 22 December 2006 6 of 11 PESD2CAN NXP Semiconductors 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. SPLIT CANH RT/2 CAN BUS TRANSCEIVER CAN bus RT/2 CANL Common mode choke (optional) 2 1 CG PESD2CAN 3 006aaa942 Fig 10. Typical application: ESD protection of two automotive CAN bus lines 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. The path length between the PESD2CAN 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. PESD2CAN_1 Product data sheet (c) NXP B.V. 2006. All rights reserved.
