When there is a problem with the fast recovery diode circuit, we usually measure it through a multimeter. Do you know the reason for the damage to the fast recovery diode?
1.The voltage used is too high, exceeding the reverse breakdown voltage of the fast recovery diode, resulting in breakdown.
2. Excessive current can cause the current through the fast recovery diode to exceed its rated current for a long time, leading to overheating and burnout, 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 specification and model of the fast recovery diode do not match. When replacing a new diode, mistakenly replacing a tube with parameters that do not meet the requirements or making wiring errors can cause the diode tube to break down and be damaged.
5.Circuit board short circuit, caused by water after cleaning the circuit board with steam and not drying it out. After cleaning with steam, please blow it again with compressed air before testing to avoid such damage.
