Jap Sega Saturn PSU repair

Hello everyone!, I am having a hard time trying to fix the psu from my japanese sega saturn, model 1, I think that the power transistor went bad, this transistor is named C5215, sadly not datasheet is available online :(

The console has the problem of wavy lines affecting the video output, very similar problem that occurs on model 2, that you just fix it by replacing the Top202yai component, I think this PSU present the same illness

Anyway, knowing that this site is where hardcore sega saturn fans reunited, could you lend me a hand on this? Does anyone know what it will a today replacement for the C5215?
