A semiconductor device () is formed on a substrate () that has first and second well regions () formed at a surface () of the substrate. A control electrode () extends over the surface to activate a first channel () with a control signal (V) for routing a current (I) from a first node () of the semiconductor device to an edge () of the first well region. The control signal further activates a second channel () for routing the current from an edge () of the second well region to a second node () of the semiconductor device.
