JFETs

A JFET is a four-terminal device, the terminals are called the gate, drain, source and body. The body terminal is always connected to the source. There are two types of JFETs and N-Channel P-Channel. FET stands for junction field-effect transistor. They can also be referred to as a JUGFET

N-Channel JFET Construction

The name N-Channel signifies that the electrons are the majority ...
