While I was going through the reference design of UCC28810 in application note SLUA752, I have a doubt regarding the secondary side diode (output diode ) selection.!
In the application note SLUA752 page 3 , output diode ( D4 ) part number is STTH1008DTI which have the Forward current rating of 10A, there the design is for 70W which 106 VDC and 600mA Current!
1. I would like to know why that much high rated diode is being used there, what are consideration to choose that part number?
2. Can I used some MUR420 or ES3J in parallel instead of that part number?
I would be grateful if you could help me with relevant information and educate me.
Thanks in advance
