Noun
JFET (plural JFETs)
(electronics) Initialism of junction field effect transistor.
Comparison of enhancement-mode and depletion-mode MOSFET symbols, along with JFET symbols. Source: Internet
If a potential difference of the proper polarity is applied between its gate and source terminals, the JFET will be more resistive to current flow, which means less current would flow in the channel between the source and drain terminals. Source: Internet
Some JFET devices are symmetrical with respect to the source and drain. Source: Internet
Structure The JFET is a long channel of semiconductor material, doped to contain an abundance of positive charge carriers or holes (p-type), or of negative carriers or electrons (n-type). Source: Internet
The flow of water through a hose can be controlled by squeezing it to reduce the cross section and the flow of electric charge through a JFET is controlled by constricting the current-carrying channel. Source: Internet
The triode is very similar in operation to the n-channel JFET ; it is normally on, and progressively switched off as the grid/gate is pulled increasingly negative of the source/cathode. Source: Internet
