Class D using PQFN 5X6 mm MosFets
In my quest for making an all SMD Class D amp (see other post) I found that you can get some really good new Fets in very small PQFN 5x6mm packages. Some even come with a dual cooling option where you have a cooling pad on top as well as on the bottom. Gives a lot of opportunities. I decided to try out some of these fets, namely the FDMS86200DC from Onsemi, which is a super fast 150 V, 35 A, 18 mOhm fet. As it is only 150V the power in 8 ohm will be limited, but still using … Continue reading Class D using PQFN 5X6 mm MosFets
