5 ? 2012 semtech corp. www.semtech.com UCLAMP0511PQ protection products applications information device connection options these tvs diodes are designed to protect one data, i/o, or power supply line. the device is bidirectional and may be used on lines where the signal polarity can go above and below ground. circuit board layout recommendations for suppression of esd. good circuit board layout is critical for the suppression of esd induced transients. the following guidelines are recommended: place the tvs near the input terminals or connectors to restrict transient coupling. minimize the path length between the tvs and the protected line. minimize all conductive loops including power and ground loops. the esd transient return path to ground should be kept as short as possible. never run critical signals near board edges. use ground planes whenever possible. equivalent circuit diagram
