prasi, can suggest different MOSFETs for your PCB? coz I can't find them on farnell.

this one?

I tought your pcb uses smd mosfets?

 

[prasi]

which ones did you get?
i have both smd and tht versions of pcbs.
if your pcb is smd, then pl refer schematic below for smd mosfet options

Thank you very much Prasi! One question: having a look at the 3D model of the THT rectifier, I noted the presence of some SMD components on the back side of the PCB. Do the PCB come with those components already soldered? Does the BOM in the OP refer to the THT rectifier? On its back side I see a big resistors which isn't present in the BOM. Can you give me some clarifications?

Thank you,
Gaetano.

 

[prasi]

Those smd components are the optional quasimodo snubbers that you can do without.
Simple, no-math transformer snubber using Quasimodo test-jig

the big THT resistor on bottom is for the led . you can calculate based on your voltage. this is also optional. (V-Vfled)/Iled. you can keep Iled to 2-5 mA

From 3D pcb model, this led resistors seems rather big (likely 1 or more watts). 1/4 or at most 1/2 could be enough?

Thank you,
Gaetano.
