The phrase "a function of the current density" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in physics or engineering, to describe how one variable depends on the current density.
Example: "The resistance of the material is a function of the current density applied to it."
Alternatives: "dependent on the current density" or "related to the current density."
