How many FET transistors are there

FET - field effect transistor / unipolar transistor

The current flow through the conductive channel of the field effect transistor is controlled by an electric field. The electric field is influenced by an applied voltage on the control electrode.

There are the following field effect transistors:

connections


The connections in the FET are called differently than in the bipolar transistor. The connections have a different meaning due to different physical properties.
The gate, or G for short, is the control electrode. The drain, or D for short, is comparable to the collector. The electron current flows through this connection. The source, or S for short, is comparable to the emitter. There the electron current flows into the FET.
