Dear Team,
My customer is using LM5574 in their MP products.
They find out one if the customer's return the diode is EOS(Electrical Over Stress).
Do you have any ideas why the diode here will short circuit?

Dear Team
The diode they are currently using B170/B - B1100/B

I would try to measure the SW pin voltage with a 'scope to see if there are no
over-voltage spikes. If the diode is rated for the input voltage and current limit, and there are no
spikes, then the diode may not be able to stand the dv/dt on the SW node.
