What is a bipolar transistor, its structure, classification, and basic principles 3

Design process of BJT

The design process of BJT includes steps such as circuit analysis, selection, circuit design, and circuit testing.transistor

Circuit analysis refers to the analysis of circuits to understand their properties and characteristics. Selection refers to choosing the appropriate BJT model based on circuit requirements. Circuit design refers to designing a circuit that meets the requirements of the circuit. Circuit testing refers to testing the designed circuit to verify its performance and characteristics.

Precautions for BJT

When using BJT, the following points should be noted:

1. Avoid exceeding the maximum withstand voltage and maximum withstand current.

2. Avoid excessively high temperatures that exceed the maximum operating temperature.

3. Avoid excessive bias to avoid affecting the operation of BJT.transistor

4. Pay attention to the pin connections of BJT to ensure normal operation.

The Development History of BJT transistor

BJT was invented by William Shockley, John Bardeen, and Walter Brattain at Bell Laboratories in the United States in 1947. It is the first semiconductor device, marking the birth of semiconductor device technology. With the continuous development of technology, the process and performance of BJTs have been continuously improved, gradually becoming one of the most widely used devices in modern electronic devices.transistor
