What are the common faults of a voltage regulator diode?

The faults of a voltage regulator diode are mainly manifested in the following aspects:

Open circuit fault: When a voltage regulator diode has an open circuit fault, it will cause the power supply voltage to rise. This is because the voltage regulator diode should play a role in stabilizing the voltage in the circuit. When it is open circuit, it loses this function, causing the power supply voltage to rise without constraint.

Short circuit fault: When a voltage regulator diode has a short circuit fault, the power supply voltage will drop to zero volts or the output will be unstable. This is because the short circuit prevents the voltage regulator diode from working properly, thereby unable to provide a stable voltage reference for the circuit.

Unstable regulated value: Another common fault of voltage regulator diodes is the instability of the regulated value. This may be due to aging of the internal components of the voltage regulator diode, temperature changes, or working voltage or current exceeding the rated value. The instability of the regulated value will affect the stability and reliability of the circuit, and may even cause the circuit to fail to work properly.

To trouble shoot the faults of a voltage regulator diode, it is necessary to first determine whether the voltage regulator diode is faulty, which can be judged through testing and detection methods. If a fault is found in the voltage regulator diode, it needs to be replaced or repaired promptly to ensure the stability and reliability of the circuit.

In addition, voltage regulator diodes have some special applications in circuits, such as series connection in both forward and reverse directions, which can act as overvoltage protection to limit voltage damage to sensitive components in the circuit. Therefore, it is very important to use voltage regulator diodes reasonably in circuit design.
