The areas of operation for a transistor switch are known as the Saturation Region and the Cut-off Region.

Thus the "saturation" voltage of a Darlington transistor is one V BE (about 0.65 V in silicon) higher than a single transistor saturation voltage, which is typically 0.1 - 0.2 V in silicon. For equal collector currents, this drawback translates to an increase in the dissipated power for the Darlington transistor over a single transistor.

The saturation voltage (VSAT) is graphically found by locating the intersection of the straight portions of the excitation curve on log-log axes [3]. Excitation Voltage (V) Fig. 3.Overcoming the threshold voltage is much easier around the source because the source is at a lower potential than the drain. Now it becomes the same story as the JFET - if the drain voltage rises then the pinch-off is more pronounced and current remains largely constant. For a bipolar transistor, saturation means something else.This assists in easing the voltage stress. With time, the open circuit voltage will probably negotiate to between 3.70V and 3.90V/cell.
