Hello,

I have problem to find a replacement of the power mosfet MTP6N56
(Q9070 on the schematic). Do you know if I could replace this TO220
mosfet by a more classical and easy to find BUZ80A for example ?
Thanks for your help,

Dominique

Hi Dominique
I would only use a TO220 package device as it's at mains potential and the
design is approved with only that style of device.
You can use any number of N channel FET's like the 6N60 or IRF820 (anything
rated at 6-8A 600 to 800V)
