The N-channel transistor has lower on-resistance and gate capacitance for the same die area. Thus an n-channel device is faster than a p-channel device. The mobility of electrons, which are carriers in the case of an n-channel device, is greater than that of holes, which are the carriers in the p-channel device. In an NMOS, the channel is an n-type silicon region connecting the highly doped n-type source and the n-type drain regions on the top of a p-type substrate. The depletion-mode MOSFET has a physically implanted channel connecting the source side and the drain side. In either case, the current's direction in the base is the same as the collector. The Bipolar Junction Transistor (BJT) is a current-driven device (in contrast, MOSFET is voltage-driven) that is widely used as an amplifier, oscillator, or switch, amongst other things. What is the difference between Transistor and MOSFET? When the MOSFET is activated and is on, the majority of the current flowing are electrons moving through the channel. Sometimes it is also known as a metal-insulator field-effect transistor (MIFET).Ī N-Channel MOSFET is a type of MOSFET in which the channel of the MOSFET is composed of a majority of electrons as current carriers. This type of transistor is also known as an insulated-gate field-effect transistor (IGFET).

Maximum Power Dissipation Derate above 25☌ Maximum Lead Temperature for Soldering Purposes, 1/16" from Case for 10 Seconds ■ Voltage controlled small signal switch. ■ High density cell design for low RDS(ON). They can be used in most applications requiring up to 500mA DC. These products are particularly suited for low voltage, low current applications such as small servo motor control, power MOSFET gate drivers, and other switching applications. These products have been designed to minimize on-state resistance while provide rugged, reliable, and fast switching performance. These N-Channel enhancement mode field effect transistors are produced using Fairchild's proprietary, high cell density, DMOS technology.
