What is a crystal diode? The basic structure, principle, classification, application, identificationethod, detection and selection method of crystal diodes 3

5、 Identification method:

1. Appearance recognition: Crystal diodes typically have a slender positive (anode) lead and a short negative (cathode) lead. The positive electrode lead is generally marked with an arrow or marked end, while the negative electrode lead is the other end. In addition, it can also be identified by features such as size, shape, and color of the appearance.

2. Component identification: Crystal diodes are usually labeled with information such as model, manufacturer, batch, etc. on the housing. You can identify it by consulting relevant information or asking the manufacturer.

3. Data manual: Detailed parameters and specifications of crystal diodes can usually be found in their data manuals. You can search for accurate information by model or manufacturer name.

6、 Testing:

1. Positive voltage measurement: Use a multimeter or digital voltmeter to connect the positive lead to the positive pole and the negative lead to the negative pole, and then measure the voltage. If the measured voltage is within the normal operating range, it indicates that the diode is functioning properly. Otherwise, there may be a malfunction.
