What is a unipolar transistor? The basic structure, working principle, classification, advantages, causes of faults, and maintenance methods of unipolar transistors 3

5、 Reason for malfunction:

The main causes of faults in unipolar transistors include the following:

1. Overload: When the current or voltage exceeds the rated value of a unipolar transistor, it may cause structural damage and lead to faults.

2. Excessive temperature: Excessive temperature can cause melting or oxidation of the internal materials of unipolar transistors, thereby affecting their normal operation.

3. Voltage too high: When the input voltage exceeds the withstand voltage range of a unipolar transistor, it may cause breakdown or burnout.

4. Excessive current: When the input current exceeds the maximum rated current of a unipolar transistor, it may cause burnout.

5. Other reasons, such as electromagnetic interference and electrostatic discharge, may also cause malfunctions in unipolar transistors.

6、 Repair method:

The maintenance methods for unipolar transistor mainly include the following aspects:

1. Check the wiring: First, check whether the wiring of the unipolar transistor is correct, whether there is looseness or poor contact. If any problems are found, the connector should be reconnected or replaced.
