What are the reasons for the burst of the fast recovery diode?

1. If the voltage is too high and exceeds the reverse breakdown voltage of the fast recovery diode, it will be broken down.

2. The current is too high, and the current through the fast recovery diode exceeds its rated current for a long time, resulting in overheating and burning, which is a common cause.

3. Buying low-frequency diodes for use in high-frequency circuits can cause the diodes to overheat and burn out.

4. The specifications and models of the fast recovery diode do not match. When replacing a new diode, mistakenly replacing a tube with one that does not meet the required operating parameters or wiring errors can cause breakdown and damage to the diode tube.

5. Circuit board short circuit, caused by water causing circuit short circuit fault after steam cleaning the circuit board without drying. Please clean it with steam and blow it again with compressed air for further testing to avoid such damage.
