Transistors are a type of active electronic components which are widely used in various electronic circuits and systems. FETs - field effect transistors, MosFETs - metal-oxide semiconductor field-effect transistors are two types of transistors that are used in different applications. FETs and MosFETs have different working principles and applications. The 2SJ438,MDKQ(J is a single, metal-oxide semiconductor field-effect transistor which is used in power control and amplification of audio signals.

Working Principle of 2SJ438,MDKQ(J

The 2SJ438, MDKQ(J is a type of single channel, enhancement MOSFET with an insulated gate. It is used for high speed switching operations and also in many amplifiers. It has a high input impedance and low output impedance which helps it to control or switch large currents with low voltages. The working principle of 2SJ438,MDKQ(J involves the control of electron flow from the source to the drain in an insulated gate.

In the input mode, the gate is connected to a voltage source and the voltage is measured at the drain and source pins. A voltage difference between the gate and drain pins induce a current flow across the channel and an electric field electrostatically generated by the gate attracts the electrons and this enables current conduction across the channel.

In the output mode, the voltage between the source and gate is measured and the electron flow is dependent on it. An increase in the source-gate voltage causes an increase in the current passing through the channel and this results in increased power dissipation.
