Dirac equation for a charged particle in static electromagnetic field iswritten for special cases of spherically symmetric potentials. Besides the wellknown Dirac-Coulomb and Dirac-Oscillator potentials, we obtain a relativisticversion of the S-wave Morse potential. This is accomplished by adding a simpleexponential potential term to the Dirac operator, which in the nonrelativisticlimit reproduces the usual Morse potential. The relativistic bound statesspectrum and spinor wavefunctions are obtained.Comment: Erratum: The last statement above Eq. (1) is now corrected and  replaced by two new statement
