Topdiode Transistor Applications
A transistor is a semiconductor device used to amplify or switch electrical signals and power. Typically, transistors consist of three layers, or terminals, of a semiconductor material, each of which can carry a current.
When working as an amplifier, a transistor transforms a small input current into a bigger output current. As a switch, it can be in one of two distinct states — on or off — to control the flow of electronic signals through an electrical circuit or electronic device.
The most basic and important characteristic of the transistor: the transistor has a current amplification effect. Its essence is that the transistor can control a large change in the collector current with a small change in the base current.
It has three major applications:
1. Used in amplifier circuits for voltage or current amplification;
2. Used in oscillation circuits for modulation, demodulation or self-oscillation;
3. Used in switching circuits as thyristors, current limiting or switching tubes.
1. Provide signal amplification to ensure a fair output for the application.
2. Regulate an incoming signal’s current and voltage.
3. Smaller and lighter than vacuum tubes, while also being mechanically stronger.
4. Require no external heating for operation.
5. A low-voltage supply is sufficient to operate a transistor.
6. Highly suitable for low-power applications.
7. Ideal for integrating with resistors and diodes to create integrated circuits.
8. As the size of transistors decreased exponentially, their cost has fallen.
