These legs are called the Gate, Drain and Source. As a transducer driver the MOSFET can be used to control powerful devices requiring large currents.Īn n-channel MOSFET has three terminals or, in other words, three legs. MOSFETs are voltage operated devices.Īn n-channel MOSFET can be thought of as a simple electronic switch or transducer driver. A MOSFET is just one example of a Field Effect Transistor (FET) and all these devices rely on the electric field due to a voltage. The n-channel MOSFET is usually just referred to as a MOSFET. OverviewĪn n-channel MOSFET is an active circuit component with three legs and usually made from silicon. As transducer drivers, MOSFETs tend to be better at handling high currents than bipolar transistors but bipolar transistors are better suited to low voltage circuits. MOSFETs are operated by voltages and can be either n-channel or p-channel MOSFETs. Bipolar transistors are devices that are operated by current. Bipolar transistors can be either npn type or pnp type. ![]() There are two distinct types of transistor, the bipolar transistor and the MOSFET, and for each type of transistor there are two varieties. Transistors are devices that require only small input currents or voltages but can handle large output currents. Something needs to allow the process devices to work with the output transducers and this is where transistors are used. The output transducers may, on the other hand, require larger currents (several amps) and work at higher voltages. The devices used to perform the various processes are often small low power ICs that can only source or sink relatively small currents (several mA) and work at fairly low voltages. By considering a systems approach to electronics, processes such as counters and logic circuits often need to drive larger output devices such as bulbs, motors and heaters etc. The above is a fairly concise description of what transistors do. They deal with electrical power in response to electrical signals. Transistors are devices that are used to drive output transducers. ![]()
