Objective data sheet Rev. 01 -- 25 January 2005 6 of 12 Philips Semiconductors PESD1CAN CAN bus ESD protection diode in SOT23 7. Application information The PESD1CAN is designed for the protection of two automotive CAN bus lines from the damage caused by ElectroStatic Discharge (ESD) and surge pulses. The PESD1CAN provides a surge capability of up to 200 W per line for a 8/20 s waveform. line 1 to be protected line 2 to be protected PESD1CAN GND 006aaa260 Fig 7. 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 protection device as close to the input terminal or connector as possible. 2. The path length between the protection device and the protected line should be minimized. 3. Keep parallel signal paths to a minimum. 4. Avoid running protection conductors in parallel with unprotected conductor. 5. Minimize all printed-circuit board 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 printed-circuit boards, use ground vias. 9397 750 14197 (c) Koninklijke Philips Electronics N.V. 2005. All rights reserved.
