A supercurrent device includes a shunt conductance across an interfacial region having a finite zero voltage current characteristic of, but not limited to. Josephson tunnel junctions. The effect of the conductance is to raise the switchback current to convenient and controllable values and simultaneously to decrease the capacitive time constant associated with the device.
