Triode Common Classification Introduction

2018-05-16

Transistor, full name should be a semiconductor transistor, also known as bipolar transistor, transistor, is a semiconductor device to control the current role is to amplify the weak signal into a larger amplitude of the electrical signal, also used as a non-contact switch. There are seven types of common classifications.


1、the material division

 

Divided by material, the triodes can be divided into triodes of silicon tube material and triodes of tritium tube material.

 

2、according to the structure

 

According to the structural division, the triode can be divided into two kinds of NPN triodes and PNP triodes.

 

3、divided by function

 

According to the function division, the triode can be divided into switch tube, power tube, Darlington tube, photosensitive tube and so on.

 

4、divided by power

 

According to the power division, the triode can be divided into three types: low power tube, medium power tube, and high power tube.

 

5、according to the operating frequency

 

According to the operating frequency, the triode can be divided into three types: low-frequency tube, high-frequency tube, and over-frequency tube.

 

6、according to the structural process

 

According to the structural process, the triode can be divided into two types: alloy tube and plane tube.

 

7、according to the installation method

 

According to the installation method, the triode is divided into plug-in triode and patch triode.
