WebThe D-MOSFET can be operated in either of two modes—the depletion mode or the enhancement mode, depending on the gate voltage, and is sometimes called a depletion/enhancement MOSFET. The n-channel MOSFET operates in the depletion mode when a negative gate-to-source voltage (V GS ) is applied and in the enhancement WebWikiZero Özgür Ansiklopedi - Wikipedia Okumanın En Kolay Yolu . MOSFET showing gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (pink).

JFETs are therefore known as depletion mode devices. This depletion region produces a potential gradient which is of varying thickness around the PN-junction and restrict the current flow through the channel by reducing its effective width and thus increasing the overall resistance of the channel itself.
