Mosfet – Electronic Parts Sourcing

What is MOSFET?

MOSFET refers to a metal-oxide-semiconductor field effect-transistor. What this means is that MOSFET acts as a field effect transistor that uses the voltage to determine the conductivity of a device. In addition to gauging the conductivity, the MOSFET can also be used for amplifying and switching signals, which in turn can be used as a transistor in digital circuits. As MOSFET transistors can be built with p-type or n-type semiconductors, complementary pairs of MOS transistors can also be utilized for making switching circuits with very low power consumption.


There are many reasons as to why it would be advantageous to use MOSFET. The most obvious reason is that they are particularly useful for amplifier applications because of MOSFET’s input impedance being nearly infinite. This allows the amplifier to encapsulate nearly all incoming signals. One of the biggest advantages is that MOSFET, when compared with bipolar transistors, requires virtually no input current to monitor load current.

MOSFETs are available in two basic forms which are the depletion type and the enhancement type. In regards to the former, the transistor needs a VGS (voltage gate source) to turn the device switch off. This is equivalent to a switch that is “normally closed.” As for the latter, the transistor requires a VGS to switch the device “ON”. The enhancement mode MOSFET is equivalent to a “Normally Open” switch.
