Catalysis of the transmembrane transfer of an ion by a voltage-gated channel. An ion is an atom or group of atoms carrying an electric charge by virtue of having gained or lost one or more electrons. Catalysis of the energy-independent passage of cations across a lipid bilayer down a concentration gradient. Catalysis of facilitated diffusion of a sodium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. Catalysis of the transmembrane transfer of a sodium ion by a voltage-gated channel. Catalysis of the transmembrane transfer of a cation by a voltage-gated channel. A cation is a positively charged ion.
