Hi You *really* need to keep the baseplate of the FRK series devices down. Their reliability drops quite a bit as you go from 40 to 50 to 60 C on the baseplate. I would avoid boosting the input voltage without a very good heatsink ( or heatsink + fan ) setup.
I’ve …. ummm ….. cooked … a number of FRK’s over the years.
