Transistors can be found in computer memory chips, cell phones and car engines, among other applications. The most common type of transistor is the metal-oxide- semiconductor field-effect transistor (MOSFET), which is widely used in electronic devices such as computers, smartphones and televisions.
11 wrz 2024 · Deeply embedded in almost everything electronic, transistors have become the nerve cells of the Information Age. There are typically three electrical leads in a transistor, called the emitter, the collector, and the base—or, in modern switching applications, the source, the drain, and the gate.
Transistors are commonly used in digital circuits as electronic switches which can be either in an "on" or "off" state, both for high-power applications such as switched-mode power supplies and for low-power applications such as logic gates.
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.
How are transistors used in power electronics? Power electronics, such as power supply units or audio amplifiers, require transistors. Their ability to switch high amounts of power on and off quickly lets them control the flow of electrical power in these devices while minimizing risks.
6 sty 2018 · 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.
