A transverse mixed spin-1/2 and spin-S<sub>B</sub> Ising model on the honeycomb lattice is studied by the use of a generalized star-triangle transformation which maps the model on an exactly solvable Ising model. The exact results for the phase diagram, compensation temperature, magnetization and transverse susceptibility are obtained and discussed.
