The advantage of a transistor is that you can use a small current or voltage to control a much larger current and voltage. That’s super useful if you want to control things like motors, high-power LEDs, speakers, relays, and more from a Raspberry Pi/Arduino/microcontroller.

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. 2018-01-06 · A transistor is an electronic component used in a circuit to control a large amount of current or voltage with a small amount of voltage or current. This means that it can be used to amplify or switch (rectify) electrical signals or power, allowing it to be used in a wide array of electronic devices. 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.

That’s super useful if you want to control things like motors, high-power LEDs, speakers, relays, and more from a Raspberry Pi/Arduino/microcontroller. A transistor is a semiconductor device with at least three terminals for connection to an electric circuit.In the common case, the third terminal controls the flow of current between the other two terminals. In small, discrete quantities, transistors can be used to create simple electronic switches, digital logic, and signal amplifying circuits. In quantities of thousands, millions, and even billions, transistors are interconnected and embedded into tiny chips to create computer memories, microprocessors, and other complex ICs. Transistor logic gates these days are usually made out of MOSFETs, and more specifically CMOS.

A transistor is a miniature electronic component that can do two different jobs. It can work either as an amplifier or a switch: When it works as an amplifier, it takes in a tiny electric current at one end (an input current) and produces a much bigger electric current (an output current) at the other.

20. Operational Amplifiers (Op-Amps).

Suppose that you have a FM receiver which grabs the signal you want. The received signal will obviously be weak due to the disturbances it would face during its journey.

Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged 

Transistors can be damaged by heat when soldering or by misuse in a circuit. If you suspect that a transistor may be damaged there are two easy ways to test it: Testing NPN Transistor 1. Testing with a multi-meter. Use a multimeter or a simple tester (battery, resistor and LED) to check each pair of leads for conduction.

Analog Devices SSM2212 is available at Mouser and features a dual, NPN-matched transistor pair specifically designed to meet the requirements of ultralow 

The received signal will obviously be weak due to the disturbances it would face during its journey. Diodes -- A transistor is a semiconductor device, just like a diode. In a way, it's what you'd get if you stacked two diodes together, and tied their anodes together. Understanding how a diode works will go a long way towards uncovering the operation of a transistor.
