In the 1980s, the advent of high-power MOSFETs made power switching more efficient and faster. Almost all modern switching power supplies use some form of power MOSFET as the switching element. MOSFETs are preferred due to their low conduction and switching losses, and the DC gate current is zero because gate MOSFETs are made up of capacitors. IRF series N-channel Power MOSFETs are developed to control DC fans, the light intensity of LED strips, and DC motors without a relay. This article gives … [Read more...]
What is Enhancement MOSFET & Its Operation
Transistors are the most popular semiconductors in the field of electronics. These are available in various types and configurations such as Bipolar-Junction Transistors (BJTs) and the Field-Effect Transistors (FETs) considered as the basic ones. These FETs are further classified as Junction field-effect transistors (JFET) and insulated gate field-effect transistors (IGFET). The transistor with input at the gate is insulated electrically from the main channel of current-carrying is referred to … [Read more...]
What is P-Channel MOSFET : Working and Its Characteristics
P-Channel MOSFET is a classification of Metal Oxide Semiconductor Device. This consists of the n-substrate in the middle with light doping concentration. These are the three terminals devices. It possesses uni-polar characteristics because its operation is dependent on the majority of the charge carriers. In this, the majority of the carriers are holes because of two p materials utilized in the circuitry. It is further classified based on the existence of the channels. If the channel exists by … [Read more...]
MOSFET as a Switch and Its Characteristics
MOSFET Switch is a metal oxide semiconductor device that consists of three terminals known as source, gate, and the drain. It comes under the classification of basic field-effect transistor (FET). The conduction is either dependent on the flow of electrons or holes as per the type of the channel. This makes the device to be unipolar. Other than three terminals there exists one more type of terminal that is referred to as the substrate or the body but it is neither used in input nor output … [Read more...]
What is MOSFET : Working and Its Applications
MOSFET is a metal oxide semiconductor that is under the category of the field-effect transistor (FET). These transistors are widely used under the varieties of the applications relating to the amplification and the switching of the devices. Because of its fabrication MOSFET's are available in smaller sizes. It consists of a source, drain, gate and the substrate of the transistor as its terminals. For the circuitry of analog or it be digital this one is the widely preferred transistor. Based on … [Read more...]
