  Weakly Interacting Massive Particles (WIMPs) and axions are arguably the most
compelling dark matter (DM) candidates in the literature. Here, we consider a
model where the PQ symmetry solves the strong CP problem, generates radiatively
Dirac neutrino masses, and gives origin to multicomponent dark sector.
Specifically, scotogenic Dirac neutrino masses arise at one-loop level. The
lightest fermionic mediator acts as the second DM candidate due to a residual
$Z_2$ symmetry resulting from the PQ symmetry breaking. The WIMP DM component
resembles the well-known singlet-doublet fermion DM. While the lower WIMP dark
mass region is usually excluded, our model reopens that portion of the
parameter space (for DM masses below $\lesssim 100$ GeV). Therefore, we perform
a phenomenological analysis that addresses the constraints from direct searches
of DM, neutrino oscillation data, and charged lepton flavor violating (LFV)
processes. The model can be tested in future facilities where DM annihilation
into SM particles is searched for by neutrino telescopes.
