A capacitor sharing surge protection circuit for protecting multiple ports from harmful energy surges, such as electrostatic discharge (ESD) and cable discharge events (CDE), is provided. The protection circuit includes a plurality of diodes with respective cathodes and anodes. Each anode of the plurality of diodes is coupled to one of the plurality of ports. A bypass capacitor is coupled between the cathodes of the plurality of diodes and ground. In an embodiment, a bulk capacitor is further coupled between the cathodes of the plurality of diodes and ground.
