Common types and main classifications of transistors

Transistors are semiconductor devices driven by current, used to control the flow of current, used to amplify weak signals, used as oscillators or switches, and have multiple functions such as detection, rectification, amplification, switching, and voltage stabilization.

The following briefly introduces the common types and main classifications of transistors.

Common types

Semiconductor triode, power transistor, phototransistor, bipolar transistor, bipolar junction, field effect transistor, electrostatic induction, single electron transistor, IGBT.

main category

According to the material, it can be divided into silicon material transistor and germanium material transistor.

According to the operating frequency, it can be divided into low-frequency transistors, high-frequency transistors and ultra-high-frequency transistors.

According to the current capacity, it can be divided into low-power transistors, medium-power transistors and high-power transistors.

According to the manufacturing process, it can be divided into diffusion transistors, alloy transistors, and planar transistors.

According to the package structure, it can be divided into metal package transistors, plastic package tubes, glass shell package transistors, etc.

According to the function and application, it can be divided into low-noise amplifier transistors, medium-high frequency amplifier transistors, low-frequency amplifier transistors, switching transistors, microwave transistors, photosensitive transistors, magnetosensitive transistors, etc.
