What is a power transistor? The basic structure, characteristics, working principle, applications, driving protection, installation points, circuit analysis, and development history of power transistors 5

In 1952, researchers at Bell Laboratories in the United States first proposed the concept of PNP power transistors, but their performance was very limited. In 1956, researchers from General Electric developed the first practical power transistor, called the Darlington transistor. The Darlington transistors, utilizes a dual transistor structure to improve the performance of power amplifiers.

In the 1960s, significant breakthroughs were made in the development of power transistors,. Researchers from Westinghouse Electric Company in the United States have proposed for the first time the MOSFET (Metal Oxide Semiconductor Field Effect Transistor) structure, which can achieve higher power and higher frequency operation.

In the 1970s and 1980s, the technology of power transistors was further improved. With the rapid development of microelectronics technology, the size of power transistors has decreased, power density has increased, and efficiency has also been significantly improved.

At present, power transistors, have become key components for various power applications, such as electric vehicles, solar power generation, power systems, etc. With the continuous advancement of semiconductor technology, the performance of power transistors will be further improved.
