Is the fast recovery diode easy to break?

Generally speaking, fast recovery diode used according to specifications are very stable, and physical damage cannot be ignored. When the positive and negative stages of the diode are reversed and the voltage and current exceed the standard, it is easy to cause diode damage. During the use of diodes, the following situations may also lead to damage or failure.

1. Inadequate lightning protection and overvoltage protection measures.

2. Under harsh operating conditions, diodes operate at high voltage for a long time, which accelerates their aging and leads to premature breakdown and damage.

3. Poor operational management. Overvoltage will cause breakdown and damage to the rectifier .

4. The equipment installation or manufacturing quality is not up to standard.

5. The diode specifications and models do not match. When replacing a new rectifier , mistakenly replacing the  with one that does not meet the required operating parameters or wiring errors can cause diode breakdown and damage.

6. The safety margin of the diode is too small. The overvoltage and overcurrent safety margin of the rectifier  is relatively small.

fast recovery diode quality detection

Place the multimeter in the Rx1k position and measure the forward and reverse resistance of the fast recovery diode. The forward resistance is usually a few ohms, and the reverse resistance is ∞. If the measured resistance values are both ∞ or 0, it indicates that the tested  is damaged. The  detection method for fast recovery diode is basically the same, but it is necessary to first determine which pin is the common end, and then use the above method to detect each fast recovery diode.
