What types of transistors are there?
Transistor is composed of three layers of impurity semiconductor devices, there are three electrodes, so also known as semiconductor transistor, transistor, etc., can be used for detection, rectification, amplification, switching, voltage regulator, signal modulation and many other functions. The low cost, sensitivity and robustness of transistors make them ubiquitous devices. Transistor mechatronics circuits have become electromechanical equipment control equipment to control the machine. Microcontrollers and computer programs are increasingly convenient for control systems compared to mechanical control systems. So what are the varieties of transistors? Take a look at below:
Transistors can be divided into low-noise amplifying transistors, medium and high-frequency amplifying transistors, low-frequency amplifying transistors, switching transistors, Darlington transistors, high back voltage transistors, band-stop transistors, damped transistors, microwave transistors, photosensitive transistors And many types of magnetic transistors. According to the use of transistor semiconductor data can be divided into silicon data transistor and germanium data transistor. According to the polarity of the transistor, it can be divided into germanium NPN transistor, germanium PNP transistor, silicon NPN transistor and silicon PNP transistor.
Transistor according to its structure and manufacturing process can be divided into diffusion type transistor, alloy type transistor war plane transistor. Transistors can be divided into small power transistors, medium power transistors and high power transistors according to their current capacity. Transistors can be divided into low-frequency transistors, high-frequency transistors and ultra-high-frequency transistors according to their operating frequency. Transistors can be divided into metal package (referred to as gold) transistors, plastic package (referred to as plastic) transistors, glass shell package (referred to as glass seal) transistors, external package (sheet) transistors and ceramic package transistors. Its package shape is varied.
