  We prove versions of super spin-charge separation for all three of the
symmetry groups SU(N), Sp(2N), and SO(N) of disordered Dirac fermions in 2+1
dimensions, which involve the supercurrent-algebras gl (1|1)_{N},
osp(2|2)_{-2N}, and osp(2|2)_N respectively. For certain restricted classes of
disordered potentials, the latter supercurrent algebra based conformal field
theories can arise as non-trivial low energy fixed points. For all cases with
such a fixed point, we compute the density of states exponents as a function of
N.
