What is a switching diode? The basic structure, characteristics, working principle, types, operating procedures, common problems, and development history of switching diodes 3

2. Before operation, disconnect the power supply to ensure safety. Connect the switch diode to the circuit as needed. Generally speaking, the anode is connected to the positive pole of the power supply, and the cathode is connected to the negative pole.

3. After connecting the power supply, the switch diode is controlled through an external circuit. The control method can be through the control of switches, level signals, or other components.

4. When the control signal arrives, the switch diode is in a conducting state. At this point, current can flow from the anode to the cathode, and the voltage drop is relatively low.

5. When the control signal is disconnected, the switch diode is in the off state. At this point, the current cannot pass through the diode and the voltage drop is high. When it is necessary to change the state of the switching diode, simply change the state of the control signal.

6. During operation, attention should be paid to voltage and current limitations to avoid exceeding the rated value of the switching diode, in order to prevent damage to components or circuit failures.

7. After the operation is completed, the power should be disconnected to prevent the current from continuing to flow.

6、 Common problems:

1. Current cannot flow: If current cannot pass through the switch diode, it may be due to reverse polarity connection or damage to the switch diode. Firstly, ensure that the polarity is correctly connected, that is, the anode is connected to the positive electrode and the cathode is connected to the negative electrode. If the connection is correct but the current still cannot flow, it may be a damaged switch diode that needs to be replaced.
