SU3304P2G/SAG is 4-channel voltage rail clamp ultra-high current and ultra-low leakage transient voltage suppressor, each channel has a pair of ESD discharge current steering diodes which are used for steering positive/negative discharging current to positive/negative voltage clamp pins. This device integrates a voltage-regulator tube whose leakage current is lower than 1.0μA. Generally, negative clamp pin of SU3304P2G/SAG is connected to GND plane for protecting power supply of the desired circuit because the positive discharging current flows to GND through the voltage-regulator tube.  

SU3304P2G/SAG is suitable for ESD protection of USB2.0 and data line.
