We investigated the analytical (s) over bar -wave solutions of Dirac equation for trigonometric Poschl-Teller (PT) potential under the pseudospin symmetry condition. The energy eigenvalues equation and corresponding wave functions are obtained by using the Nikiforov-Uvarov (NU) method. The energy bound states are also calculated numerically.
