What are the causes of damage to the fast recovery diodecircuit?

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 tube.

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 tube, mistakenly replacing the tube 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 tube is relatively small.
