Application information The PESD36VS2UT is designed for the protection of up to two unidirectional data or signal lines from the damage caused by ESD and surge pulses. The devices may be used on lines where the signal polarities are either positive or negative with respect to ground. The PESD36VS2UT provides a surge capability of 160 W per line for an 8/20 s waveform. line 1 to be protected line 1 to be protected line 2 to be protected PESD36VS2UT GND unidirectional protection of two lines PESD36VS2UT GND bidirectional protection of one line 006aab617 Fig 7. Application diagram 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 device as close to the input terminal or connector as possible. 2. The path length between the device and the protected line should be minimized. 3. Keep parallel signal paths to a minimum. 4. Avoid running protected 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. 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.
