The total current flowing across a p-n junction may be represented by four current components. They are:

1. Diffusion current of electrons: This is the current due to the movement of electrons from the n-region to the p-region, driven by the concentration gradient.

2. Diffusion current of holes: This is the current due to the movement of holes from the p-region to the n-region, also driven by the concentration gradient.

3. Drift current of electrons: This is the current due to the movement of electrons under the influence of the electric field within the depletion region.

4. Drift current of holes: This is the current due to the movement of holes under the influence of the electric field within the depletion region.
