The BJT remains a device that excels in some applications, such as discrete circuit design, due to the very wide selection of BJT types available, and because of its high transconductance and output resistance compared to MOSFETs. The BJT is also the choice for demanding analog circuits, especially for very-high-frequency applications, such as radio-frequency circuits for wireless systems. WebBipolar junction transistors or BJT is a semiconductor device which is structured like two p-n junction diodes connected back to back. The three leads of a BJT are Collector, base and emitter. Two types of BJT are NPN and PNP. A Bipolar Junction transistor is a current controlled device.
