Catalysis of the transmembrane transfer of a calcium ion by a voltage-gated channel across the plasma membrane of a cardiac muscle cell that contributes to the depolarization phase of an action potential. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded. (Gene Ontology, GO_0086007)
