A Guide to The Different Kinds Of Transistors

By applying a small current or voltage to the base, the transistor can control the flow of current between the emitter and collector. When used as an amplifier, the transistor increases the strength of an electrical signal, while as a switch, it can turn on and off the flow of current. Here is a super quick guide to the most commonly used transistors.

MOSFET

It has three terminals: the source, gate, and drain. The MOSFET works by controlling the flow of electrons between the source and drain terminals using an electric field created by the voltage applied to the gate terminal. MOSFETs have many applications, including amplifiers.

Phototransistor

A phototransistor is a type of transistor that is sensitive to light. It operates by using light to generate an electric current that flows between its collector and emitter terminals. The amount of current generated by the phototransistor is proportional to the intensity of light that falls on it.

JFET

Junction Field Effect Transistors work by controlling the flow of electrons between the source and drain terminals using an electric field created by the voltage applied to the gate terminal. Junction Field Effect transistors tend to be a little more expensive than MOSFET examples, but their high levels of durability and their ability to cope with high voltages make them essential in some fields.
