JFETs

JFETs A JFET is a four terminal device, the terminals are called gate, drain, source and body. The body terminal is always connected to the source. There are two types of JFETs an N-Channel & P-Channel.What does JFET stand for? JFET stands for junction field-effect transistorN-Channel JFET ConstructionThe name N-Channel signifies that the electrons are the majority charge carriers. To form the N-Channel an N type semiconductor is used as a base and doped with a P type semiconductor at both ends. Both these P regions are electrically linked together with an ohmic contact at the gate. Two further terminals are taken out at the opposite ends for the drain and the source.P-Channel JFET ConstructionThe name P channel signifies that the holes are the majority charge carriers. To form the P-Channel a P type semiconductor is used as a base and doped with an N type semiconductor at both ends. Both these N regions are electrically linked together with an ohmic contact at the gate. Two further terminals are taken out at the opposite ends for the drain and the source.Features and Benefits High input impedance Voltage controlled device High degree of isolation between the input and the output Less noiseWhat are they also known as? JUGFETWhat are JFET transistors used for? JFET transistors have many applications in electronics and communication. You can use them as an electronically controlled switch to control electric power to a load, and as amplifiers.What is the difference between a JFET & BJT (Bipolar Junction Transistor)? The main difference between a JFET and BJT is a field effect transistor only majority charge carrier flows while the BJT (bipolar transistor) offers both majority and minority charge carrier flows.What is doping of semiconductors? Doping is the process of including foreign impurities to intrinsic semiconductors to change their electrical properties. Trivalent atoms used to dope silicon cause an intrinsic semiconductor to become a P-Type semiconductor. Pentavalent used to dope silicon cause an intrinsic semiconductor to become an N-Type semiconductor.
