We present an analytic formula for the [ital O]([alpha][sub [ital s]]) corrections to the decay [ital t][r arrow][ital H][sup +][ital b] for nonzero [ital m][sub [ital H]] and [ital m][sub [ital b]]. The equivalence theorem is used to relate these corrections to those for the process [ital t][r arrow][ital W][sup +][ital b]. Contrary to previously published results we find that the effect of the [ital b] quark mass is negligible for a wide range of [ital m][sub [ital t]], [ital m][sub [ital H]], and tan[beta].
