Has anyone investigated the value of snubbers for a HEXFRED rectifier bridge? Assuming the purpose of going HEXFRED is to reduce rf hash, is snubbing still beneficial, or still a system dependent thing? I can't find any answer through a search.
According to IRF, the soft recovery means there is very little need for a RC snubber.
The junction capacitance is something like 1/10th that of an MUR860 -- i.e. about 10pF -- compared to 100pF (@30V).

I am aware of the supposed lack of RF with Hexfreds. I was wondering, though, if anyone had any experience otherwise, or if snubbing improved them even more.
