If the MOSFET is an n-channel or nMOS FET, then the source and drain are n+ regions and the body is a p region. If the MOSFET is a p-channel or pMOS FET, then the source and drain are p+ regions and the body is a n region. The source is so named because it is the source of the charge carriers (electrons for n-channel, holes for p-channel) that ...
A diode-connected transistor is a method of creating a two-terminal rectifying device (a diode) out of a three-terminal transistor. A characteristic of diode-connected transistors is that they are always in the saturation region for metal–oxide–semiconductor field-effect transistors (MOSFETs) and junction-gate field-effect transistors ...
The MOSFET is also capable of handling higher power than the JFET. [35] The MOSFET was the first truly compact transistor that could be miniaturised and mass-produced for a wide range of uses. [6] The MOSFET thus became the most common type of transistor in computers, electronics, [36] and communications technology (such as smartphones). [37]
A power MOSFET is a specific type of metal–oxide–semiconductor field-effect transistor (MOSFET) designed to handle significant power levels. Compared to the other power semiconductor devices , such as an insulated-gate bipolar transistor (IGBT) or a thyristor , its main advantages are high switching speed and good efficiency at low voltages.
The 2N7000 is an N-channel, enhancement-mode MOSFET used for low-power switching applications. [1] The 2N7000 is a widely available and popular part, often recommended as useful and common components to have around for hobbyist use. [2] Packaged in a TO-92 enclosure, the 2N7000 is rated to withstand 60 volts and can switch 200 millamps.
A semiconductor diode is a device typically made from a single p–n junction.At the junction of a p-type and an n-type semiconductor, there forms a depletion region where current conduction is inhibited by the lack of mobile charge carriers.
The low on-resistance property of a MOSFET reduces ohmic losses compared to the diode rectifier (below 32 A in this case), which exhibits a significant voltage drop even at very low current levels. Paralleling two MOSFETs (pink curve) reduces the losses further, whereas paralleling several diodes won't significantly reduce the forward-voltage drop.
Diode–transistor logic (DTL) was used in the IBM 608 which was the first all-transistorized computer. Early transistorized computers were implemented using discrete transistors, resistors, diodes and capacitors. The first diode–transistor logic family of integrated circuits was introduced by Signetics in 1962.
