NXP 7030AL - N-channel TrenchMOS logic level FET IRF640 Power Mosfet die. The power MOSFET is the most widely used power semiconductor device in the world. [3] As of 2010, the power MOSFET accounts for 53% of the power transistor market, ahead of the insulated-gate bipolar transistor (27%), RF power amplifier (11%) and bipolar junction transistor (9%).

The MOSFET is by far the most common transistor in digital circuits, as billions may be included in a memory chip or microprocessor. As MOSFETs can be made with either p-type or n-type semiconductors, complementary pairs of MOS transistors can be used to make switching circuits with very low power consumption, in the form of CMOS logic.
Enhancement-mode MOSFETs (metal–oxide–semiconductor FETs) are the common switching elements in most integrated circuits. These devices are off at zero gate–source voltage. NMOS can be turned on by pulling the gate voltage higher than the source voltage, PMOS can be turned on by pulling the gate voltage lower than the source voltage.
The MOSFET (metal–oxide–semiconductor field-effect transistor) utilizes an insulator (typically SiO 2) between the gate and the body. This is by far the most common type of FET. The DGMOSFET (dual-gate MOSFET) or DGMOS, a MOSFET with two insulated gates. The IGBT (insulated-gate bipolar transistor) is a device for power control. It has a ...
MOSFET, showing gate (G), body (B), source (S), and drain (D) terminals. The gate is separated from the body by an insulating layer (pink).. The MOSFET (metal–oxide–semiconductor field-effect transistor) [1] is a type of insulated-gate field-effect transistor (IGFET) that is fabricated by the controlled oxidation of a semiconductor, typically silicon.
In textbooks, channel length modulation in active mode usually is described using the Shichman–Hodges model, accurate only for old technology: [2] where = drain current, ′ = technology parameter sometimes called the transconductance coefficient, W, L = MOSFET width and length, = gate-to-source voltage, =threshold voltage, = drain-to-source voltage, =, and λ = channel-length modulation ...
Many other n-channel MOSFETs exist. Some part number are 2N7002, BS170, 2N7002, VQ1000J, and VQ1000P. They may have different pin outs, packages, and electrical properties. The BS250P is "a good p-channel analog of the 2N7000." [4]
LDMOS (laterally-diffused metal-oxide semiconductor) [1] is a planar double-diffused MOSFET (metal–oxide–semiconductor field-effect transistor) used in amplifiers, including microwave power amplifiers, RF power amplifiers and audio power amplifiers. These transistors are often fabricated on p/p + silicon epitaxial layers.
