JFET; a p-channel JFET can be made by transposing the p and n materials. All JFETs operate in the depletion mode, as already described. Figure 4 shows the typical transfer character-istics of a low-power n-channel JFET, and illustrates some important fea-tures of this type of device. The most important characteristics of the JFET are as follows.

Field effect transistors, FETs come in a large variety of different types. Each type of FET has its own circuit symbol, so it helps to understand the different types of FET and their circuit symbols to enable the circuits to be read accurately.

P Channel Jfet Working

Junction FETs or JFETs were the first type of FET and these have a distinctive symbol showing the diode junction. Insulated gate FETs, including MOSFETs have circuit symbols that indicate the insulation on the gate.

Obviously dual gate FETs have two gates and both need to be incorporated into the circuit symbol.
