The electroweak radiative corrections to [ital O]([alpha][ital m][sub [ital t]][sup 2]/[ital m][sub [ital W]][sup 2]) to the tree-level process [ital t][r arrow][ital H][sup +][ital b] are calculated for a heavy top quark. The corrections imply a few to 10% reduction in the partial width relative to the tree-level result, depending strongly on the parameter tan[beta] and on the top-quark mass. For some given values of tan[beta] and [ital m][sub [ital t]], the combined effect of such electroweak corrections and the QCD corrections can result in a [similar to]17% reduction in the width.
