Depletion mode A type of FET in which reverse gate-source voltage is used to deplete the channel of free carriers. These devices reduce current flow by increasing the negative voltage on the gate (assuming an N-type channel). This reduces the size of the channel and increases its resistance.  Schematic symbol for an N-channel depletion mode MOSFET Schematic symbol for a P-channel depletion mode MOSFET See also MOSFET and enhancement mode.
