Products Catalogs & Keywords:
A junction field effect transistor, commonly known as transistor JFET, represents one of the most straightforward forms of field effect transistors. Unlike Bipolar Junction Transistors (BJTs), JFETs operate as voltage controlled devices. Within the JFET structure, current flow results from the majority of charge carriers, distinguishing it from BJTs where both minority and majority charge carriers contribute to current flow.

JFET Types
Depending on the source of current flow, JFETs are classified into two types as follows:
n-channel JFET
p-channel JFET
The classification is based on whether the current flow is due to electrons or holes.
Junction Field Effect Transistor Applications
JFET is used as a switch
JFET is used as a chopper
JFET is used as a buffer
JFETs are used in oscillatory circuits
JFETs are used in cascade amplifiers
