Application information The PESD1FLEX is designed for the protection of two automotive FlexRay data lines from the damage caused by ESD and surge pulses. The device supports a FlexRay data rate of 10 Mbit/s. The PESD1FLEX provides a surge capability of up to 200 W per line for an 8/20 µs waveform. BM common mode choke (optional) FlexRay bus RT/2 FlexRay TRANSCEIVER RT/2 BP CG 2 1 PESD1FLEX 3 006aab053 Fig 8. Typical application: ESD protection of two automotive FlexRay 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 PESD1FLEX as close to the input terminal or connector as possible. 2. The path length between the PESD1FLEX 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. PESD1FLEX_2 Product data sheet © NXP B.V. 2008. All rights reserved.
