2N5639RLRAG Description

The 2N5639RLRAG is a JFET Chopper Transistor with N?Channel ? Depletion. A simple form of the field-effect transistor is the junction-gate field-effect transistor (JFET). JFETs are three-terminal semiconductor devices that can be employed as resistors, switches, or amplifier building blocks.

JFETs are purely voltage-controlled and do not require a biasing current, in contrast to bipolar junction transistors. Between the source and drain terminals, a semiconducting channel conducts an electrical charge. The channel is pinched, causing the electric current to be hindered or turned off entirely, by supplying a reverse bias voltage to a gate terminal. When there is no voltage between the source and gate terminals of a JFET, it is typically conducting.
