  We exploit the relationship between the space components of the
energy-momentum tensor and the supercurrent to discuss the connection between
the BPS equations and the vanishing of the components of the stress tensor in
various supersymmetric theories with solitons.
  Using the fact that certain combination of supercharges annihilate BPS
states, we show that $T_{ij}=0$ for kinks, vortices and dyons, displaying the
connection between supersymmetry and non-interacting BPS solitons.
