  We consider three-dimensional sQED with 2 flavors and minimal supersymmetry.
We discuss various models which are dual to Gross-Neveu-Yukawa theories. The
$U(2)$ ultraviolet global symmetry is often enhanced in the infrared, for
instance to $O(4)$ or $SU(3)$. This is analogous to the conjectured behaviour
of non-supersymmetric QED with 2 flavors. A perturbative analysis of the
Gross-Neveu-Yukawa models in the $D = 4 - \varepsilon$ expansion shows that the
$U(2)$ preserving superpotential deformations of the sQED (modulo tuning mass
terms to zero) are irrelevant, so the fixed points with enhanced symmetry are
stable. We also construct an example of $\mathcal{N} = 2$ sQED with 4 flavors
that exhibits enhanced $SO(6)$ symmetry.
