The current diodes in the LM5008 application circuit (CJ,SS510,SMAF, see attachment) will break down and short circuit after a period of use (about 1 year), resulting in circuit failure.
The input voltage of the circuit is 60V, the output voltage is 5V, and the output current is 300mA.
Do the parameters of the components in this application circuit need to be optimized?What causes diode breakdown, LM5008 is not damaged
