JFET is a 3-terminal semiconductor device that is used as amplifiers, voltage-controlled resistors, or electronically-controlled switches. Not like BJTs, these are completely voltage-controlled because they do not require a biasing current. There are various JFETs available in the market which are designed by different manufacturers. Similarly, 2N5457 N-channel JFET was manufactured by a semiconductor supplier company namely ON Semiconductor. They manufacture different products like logic, … [Read more...]
MPF102 JFET : Pin Configuration, Circuit, Working & Its Applications
In many electronic circuits like small signal amplifier circuits, switching circuits, transfer circuits, etc. Junction Field Effect Transistors (JFETs) are commonly used electronic components due to their high input impedance and low power consumption. It is a voltage-controlled resistor and it is very easy to operate in low amplifier circuits in TV or radio receivers, modulation circuits like FM, AM, SW (Short Wave), etc. Among many, let's discuss MPF102 N-channel JFET is affordable and rarely … [Read more...]
Junction Field Effect Transistor : Working, Characteristics & Applications
A JFET or Junction Field Effect Transistor is a transistor that classified under the category of FET. These are known for its voltage-controlled transistors where it doesn’t depend on the current for biasing. These consist of source, gate and drain as its terminals. This transistor comes under unipolar devices. The reason for this is that the conduction is dependent on the majority of the charge carriers. These FETs has the capability of consuming lesser amounts of power. It can be manufactured … [Read more...]
