Introduction to IRF740
- The IRF740 is an N-channel MOSFET that comes with 125W power dissipation. This is the power device dissipates during the working of this component.
- This device is mainly used for fast switching applications and comes with ultra-low on-resistance of 0.55 Ohms which is the resistance between drain and source terminals.
- The IRF740 contains three terminals named source, drain, and gate. Sometimes it is termed as a four-pin device when the body is also considered as its terminal.

- The gate terminal is located between the source and drain terminals and is the area used for biasing of the device. While the drain terminal is the location from where electrons leave the channel and the source terminal is the location from where electrons enter the channel.
- The MOSFETs are mainly categorized into two main types named N-channel MOSFET and P-channel MOSFET. This device IRF740 belongs to the N-channel MOSFET where electrons are responsible for the current flow inside the device as opposed to P-channel MOSFETs where holes are the charge carriers responsible for conductance inside the device.
- It is important to note that the movement of the electrons is better than the movement of holes inside the MOSFET. The reason N-channel MOSFETs are preferred over P-channel MOSFETs in a range of applications.
- The MOSFET operates in two modes i.e. depletion mode and enhancement mode.
- The nature of electrons is opposite in both these modes in N-channel MOSFETs. During the enhancement mode when there is no voltage, there will be no current across the channel. However, when voltage is applied across the gate terminal, it increases the movement of electrons and thus increases the conductance.
- On the other hand, during depletion mode, when there is no voltage applied across the gate terminal, there is current across the channel. However, when the voltage is applied across the gate terminal, it will decrease the movement of electrons and hence decrease the channel conductivity.

Today’s ever-growing market of the Electronics Industry is expanding to a greater extent and there has always been a special aspect of the Audio amplifiers in this industry, and for the amplification purpose, we often use Transistors for our circuit requirement.
We can use a different type of Transistors like we can use conventional BJTs (Bipolar Junction Transistors) like NPN or PNP type or we can use a special type of transistor MOSFETs (Metal Oxide Semiconductor Field Effect Transistor).
What is a MOSFET?
A metal-oxide-semiconductor field-effect transistor (MOSFET, MOS-FET, or MOSFET) is a field-effect transistor (FET with an insulated gate) where the voltage determines the conductivity of this Transistor. It is mainly used for switching or amplifying signals. The ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals.
