If the drain, source, and channel are all a p-type material, and the transistor operates in both modes, this is a p-channel E-MOSFET.

A common-drain configured JFET is also called a source-follower.

The amount of gate voltage needed to turn the JFET completely off is called V_GS(OFF).

In a voltage-divider JFET circuit, I_D is a maximum when V_GS = 0 V.

The charge carriers in a junction field effect transistor (JFET) will flow from source to drain in a p-channel and from drain to source in an n-channel.
