Hi Zanash,

I have used the Shottky 11DQ10's before, and also Ultra Fast UF4002's.

I just wondered what the soft recoverys were like.

Cheers

Dave

The schottky's will be quieter [I think] the soft recoveries are going to introduce a different level of back ground noise, as they will work more like standard diodes. As schottky's use the mass migration principle, they generate little to no back emf [which causes the noise] where as the soft recovery will produce plenty but there rececovery has a gentler slope than standard diodes. Of course I may have this completely wrapped round my neck, in which case there may be someone with more knowledge than me to explain the differences!
