The transistor, also known as a crystal triode, is a semiconductor component used for amplifying current, switching, and signal processing. The main structure of the transistor consists of a P-type semiconductor, an N-type semiconductor, and an N-type or P-type semiconductor sandwiched in between, which are respectively called the emitter, base, and collector. Below is a detailed analysis of the structure, function, and working principle of the transistor:

In electronics, rectification is the process of converting alternating current (AC) into direct current (DC). In practical circuits, rectifier circuits are required to convert AC into DC in order to supply power to electronic devices. The rectifier diode ISO124P is a component used to convert AC into DC. It is a semiconductor device, typically made of silicon or silicon carbide. The rectifier diode is a bidirectional conductive device that allows current to pass through it under forward voltage

According to data from CINNO, in the first half of 2025, there was a notable divergence in investment within China's semiconductor industry. The overall investment amounted to approximately 455 billion yuan, marking a year-on-year decrease of 9.85%. However, semiconductor equipment investment bucked the trend and increased by over 53%, signaling the accelerated rise of domestically produced equipment.

There are two types of transistor based on their materials: germanium transistor and silicon transistor. And each of them has two structural forms, NPN and PNP, but the most commonly used are silicon NPN and PNP transistors. Except for the power polarity, their working principles are the same. The following only introduces the current amplification principle of NPN silicon transistors. Principle of current amplification.
