The state of a bipolar transistor in which both the base-emitter and base-collector junctions are forward-biased. The collector-emitter voltage falls to about 0.1-0.3 V, corresponding to a switch in the on state.
Field: Bipolar transistors
With VGS > Vth and a channel present, once VDS ≥ VGS − Vth the gate-to-channel voltage at the drain end falls below Vth, the channel pinches off, and drain current becomes nearly independent of VDS—the saturation region.
