1、 Different structures

The diode rectifier structure is simple and consists of two different types of semiconductor materials, P-type and N-type. The bridge rectifier connects four diodes in series to form a whole. There are also two different semiconductor materials, P-type and N-type, inside the bridge rectifier, but they are connected together differently to form a four way rectifier circuit.

2、 Different functions

Diode rectifiers have a single conductivity and can only conduct electricity during forward bias, while blocking the passage of current during reverse bias. Its main function is to act as a rectifier, converting AC signals into DC electrical signals for subsequent circuit use.

The bridge rectifier can also achieve unidirectional current conduction, but due to the internal composition of four diodes, it can achieve a more complete rectifier circuit. Its main function is to rectify the AC signal into a complete sine wave, while also rectifying negative signals into positive values.

3、 Different application fields

Due to the fact that diode rectifiers can only perform half wave rectification conversion, their application range is relatively narrow, mainly used in low-power circuits, such as small power supplies. The bridge rectifier can achieve full wave rectification, so its application fields are more extensive and can be applied in high-power circuits, such as electronic power supplies and other fields that require high current.

4、 Different stability

There is only one PN junction inside the diode rectifier, so it is prone to failure in environments such as high temperature, high voltage, and high frequency. The bridge rectifier is composed of multiple diodes as a whole, so its stability is higher compared to a single diode.

In summary, although diode rectifiers and bridge rectifiers are commonly used components in circuits, there are significant differences in structure, function, application, and stability. When selecting circuit components, specific types of components need to be selected according to actual needs.

1. Definition and classification of semiconductor diodes

A semiconductor diode is a unidirectional conductive two-terminal device made of semiconductor materials. It is widely used in rectification scenarios because of its characteristic that only allows current to flow in a single direction. It is one of the most commonly used electronic components. The semiconductor diode is one of the earliest discrete semiconductor devices. It can be connected to a variety of components such as resistors, capacitors, and inductors in a reasonable combination to form circuits with different functions. These circuits can achieve various functions such as rectification of alternating current, wave building, amplitude limiting, clamping, and voltage stabilization of the modulated signal.

According to specific uses, diodes can be divided into detection diodes, rectifier diodes, Zener diodes, switching diodes, isolation diodes, Schottky diodes, light emitting diodes, silicon power switching diodes, rotating diodes, etc. Among them, rectifier diodes, detector diodes, switching diodes, and Zener diodes are widely used.

2. Industry chain analysis of China's semiconductor diode industry

Participants in the upstream market of China's semiconductor diode industry chain include industrial silicon, packaging materials and other raw material suppliers and production equipment suppliers. The midstream of the industry chain is a Chinese semiconductor diode manufacturer. The downstream terminal application areas of the industry chain cover consumer electronics such as mobile phones, computers, and home appliances. And automobiles and other fields.
