  We examine an extension of the Standard Model that addresses the dark matter
puzzle and generates Dirac neutrinos masses through the radiative seesaw
mechanism. The new field content includes a scalar field that plays an
important role in setting the relic abundance of dark matter. We analyze the
phenomenology in the light of direct, indirect, and collider searches of dark
matter. In this framework, the dark matter candidate is a Dirac particle that
is a mixture of new singlet-doublet fields with mass $m_{\chi_1^0}\lesssim
1.1\,\text{TeV}$. We find that the allowed parameter space of this model is
broader than the well-known Majorana dark matter scenario.
