What is meant by transistor definition?

1 : a solid-state electronic device that is used to control the flow of electricity in electronic equipment and usually consists of a small block of a semiconductor (such as germanium) with at least three electrodes. 2 : a transistorized radio.

How does a transister work?

A transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon. By turning a small input current into a large output current, the transistor acts like an amplifier. But it also acts like a switch at the same time.

What are the three types of transistor?

Transistors are broadly divided into three types: bipolar transistors (bipolar junction transistors: BJTs), field-effect transistors (FETs), and insulated-gate bipolar transistors (IGBTs). A bipolar transistor is a type of transistor that uses both electrons and holes as charge carriers.

What is the role of transistor?

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. Transistors are one of the basic building blocks of modern electronics. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.

What is 2N3055 transistor?

The 2N3055 is a silicon NPN power transistor intended for general purpose applications. It was introduced in the early 1960s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mid-1970s. Its numbering follows the JEDEC standard. It is a transistor type of enduring popularity.

What are the two main function of transistor?

A transistor is a kind of solid semiconductor device, which has many functions, such as detecting, rectifying, amplifying, switching, voltage stabilizing, signal modulating and so on. As a variable current switch, the transistor can control the output current based on the input voltage.

Why do transistors have 3 legs?

The transistor has three legs, these are the base, collector and the emitter. The base of the transistor is used to switch current through the collector and emitter. When the base is between 0V and 0.7V it is switched off and above 0.7V it is switched on allowing the current to flow from the collector to the emitter.

What are the three terminals of a FET transistor?

For FET, the three terminals are Gate, Source and Drain. The voltage at the gate terminal can control a current between source and drain. FET is a unipolar transistor in which N channel FET or P channel FET are used for conduction.

Which is an insulated gate bipolar transistor ( IGBT )?

Jump to navigation Jump to search. An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch which, as it was developed, came to combine high efficiency and fast switching.

What are the three types of transistor configuration?

This transistor is widely used in the circuit. There are three types of configuration as a common base (CB), common collector (CC) and common emitter (CE). In Common Base (CB) configuration the base terminal of the transistor is common between input and output terminals.

What kind of transistor is a metal oxide semiconductor?

The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET), also known as the metal–oxide–silicon transistor (MOS transistor, or MOS), is a type of field-effect transistor that is fabricated by the controlled oxidation of a semiconductor, typically silicon.
