Based on the concept of the SUSYQM approach and the functional analysis method, we have obtained the energy eigenvalues and the corresponding eigenfunctions of the Dirac equation under the Deng-Fan potential with the Hulthén potential as tensor interaction. We have reported the results in pseudospin and spin symmetry limits and the effect of tensor interaction is discussed. We have also discussed some special cases of Deng-Fan potential.
