6 ? 2012 semtech corp. www.semtech.com rclamp0531tq protection products applications information applications information device connection options these low capacitance tvs diodes are designed to provide common mode protection for one high-speed line or differential protection for one line pair. the device is bidirectional and may be used on lines where the signal polarity is positive and negative. circuit board layout recommendations for suppres- sion of esd. good circuit board layout is critical for the suppression of esd induced transients. the following guidelines are recommended: z place the tvs near the input terminals or connec- tors to restrict transient coupling. z minimize the path length between the tvs and the protected line. z minimize all conductive loops including power and ground loops. z the esd transient return path to ground should be kept as short as possible. z never run critical signals near board edges. z use ground planes whenever possible. equivalent circuit diagram 2 1
