What is a crystal diode? The basic structure, principle, classification, application, identification method, detection and selection method of crystal diodes 2

3、 Category:

Crystal diodes are mainly divided into two categories: small signal diodes and power diodes. Small signal diodes are suitable for low current, high-frequency applications, while power diodes are suitable for high current, low-frequency applications. According to different structures, crystal diodes can also be divided into point contact diodes, surface contact diodes, alloy contact diodes, etc.

4、 Application:

Crystal diodes have a wide range of applications in electronic devices, such as:

Signal detection: Crystal diodes can be used to detect the presence and strength of signals, commonly used in devices such as radios and televisions.

Rectification: Crystal diodes can convert AC signals into DC signals, commonly used in power supply and other applications.

Protection: Crystal diodes can be used for overvoltage protection, overcurrent protection, etc. in circuits.

● Luminescence: Crystal diodes made of certain special materials can emit visible light, used for indicator lights, display screens, etc.
