What’s a photo transistor?

A phototransistor is an electronic component that amplifies and switches current based on exposure to light. It has exposed base sections that activate the component when exposed to light. The operating range can be controlled by the intensity of light applied. It is commonly used in devices such as optical remote controls, light pulse counters, […]

What’s a unijunction transistor?

A unijunction transistor is a three-terminal semiconductor device used in low-power circuits to control or activate other electronic devices. It belongs to the thyristor family and has a single emitter junction. It can be used in relaxation oscillator circuits and trigger circuits with a capacitor. A programmable unijunction transistor, or PUT, is a special type […]

CPU Transistor: What is it?

A transistor is a semiconductor device that amplifies and switches electronic signals. It has three terminals and replaced vacuum tubes in electronic devices. A CPU transistor is part of an integrated circuit and can be a switch or amplifier. Transistors are smaller and cheaper than vacuum tubes and were invented in the 1950s. The first […]

What’s an avalanche transistor?

The avalanche transistor operates in the avalanche breakdown region, where impact ionization occurs, creating more current. It can operate in different modes and frequencies, expanding the spectrum of communication signals. Its low energy emissions do not interfere with other signals, and modulations can be adjusted. The bipolar junction avalanche transistor, or simply the avalanche transistor, […]

Transistor types: what are they?

Transistors continue to evolve with dozens of types in common use. Power bipolar transistors are used in telecommunication, RF MOSFET transistors in heavy use devices, SCR rectifiers for high voltage levels, and Darlington transistors for high current gain in a compact design. PCB elements are recommended for efficiency. Transistors are an example of an electronic […]
