Does Motorola still make transistors?
Motorola exited the Discrete transistor and diode business several years ago leaving a multitude of needs for exact replacements.
What is a transistor easy definition?
Definition of transistor 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.
What are semiconductor transistors?
A transistor is a semiconductor device used to amplify or switch electrical signals and power. The transistor is 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 electronic circuit.
What is the purpose of transistor?
transistor, semiconductor device for amplifying, controlling, and generating electrical signals. Transistors are the active components of integrated circuits, or “microchips,” which often contain billions of these minuscule devices etched into their shiny surfaces.
What semiconductor means?
semiconductor, any of a class of crystalline solids intermediate in electrical conductivity between a conductor and an insulator. Semiconductors are employed in the manufacture of various kinds of electronic devices, including diodes, transistors, and integrated circuits.
What are semiconductors examples?
Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called “metalloid staircase” on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others.
What is a PNP transistor?
In such a configuration, the device will control the flow of current. PNP transistor consists of 2 crystal diodes which are connected in series. The right side and left side of the diodes are known as the collector-base diode and emitter-base diode, respectively.
What is a transistor?
What is a Transistor? A transistor is a type of a semiconductor device that can be used to both conduct and insulate electric current or voltage. A transistor basically acts as a switch and an amplifier.
How many types of transistors are there in circuits?
Based on how they are used in a circuit there are mainly two types of transistors. The three terminals of BJT are base, emitter and collector. A very small current flowing between base and emitter can control a larger flow of current between the collector and emitter terminal.
What is an emitter in a transistor?
Emitter: It is the negative lead of the transistor. Well, the very basic working principle of a transistor is based on controlling the flow of current through one channel by varying intensity of a very smaller current that is flowing through a second channel.
