1.Processes
2.Transistors can be classified according to their structure and manufacturing process as diffusion transistors, alloy transistors and planar transistors.
3.Current Capacity
4.Transistors can be divided into low power transistors, medium power transistors and high power transistors according to their current capacity.
5.Operating Frequency
6.Transistors can be divided into low frequency transistors, high frequency transistors and ultra high frequency transistors according to their operating frequency.
7.Package Structure
8.According to the package structure, transistors can be divided into metal package (referred to as gold seal) transistors, plastic package (referred to as plastic seal) transistors, glass case package (referred to as glass seal) transistors, surface package (sheet) transistors and ceramic package transistors. The packages are available in a variety of shapes.
9.By function and application
10.Transistors can be classified by function and application into low noise amplifying transistors, medium and high frequency amplifying transistors, low frequency amplifying transistors, switching transistors, Darlington transistors, high voltage transistors, resistive transistors, damped transistors, microwave transistors, light sensitive transistors and magnetic transistors.

A transistor is a solid state semiconductor device (including diodes, triodes, field effect tubes, thyristors, etc., sometimes specifically bipolar devices) with various functions such as detector, rectifier, amplifier, switch, voltage regulator and signal modulation. As a variable current switch, the transistor is able to control the output current based on the input voltage. Unlike ordinary mechanical switches (e.g. Relay, switch), transistors use electrical signals to control their own opening and closing, so the switching speed can be very fast, up to 100GHz or more in the laboratory.
Transistors can be classified according to their function and use into various types such as low noise amplifying transistors, medium and high frequency amplifying transistors, low frequency amplifying transistors, switching transistors, Darlington transistors, high inverse voltage transistors, resistive transistors, damped transistors, microwave transistors, photosensitive transistors and magnetosensitive transistors.
