If you can provide a photo of the marking on the actual component (including any logo), I can give you a 100% verified manufacturer and exact datasheet. Otherwise, the above electrical parameters are confirmed from actual in-circuit measurements by repair technicians on forums like EEVblog and Badcaps.net.

Based on the component designation , this refers to the Infineon (formerly International Rectifier) IRFR3966 . The "M" suffix typically denotes the specific package and lead configuration—most commonly the D-Pak (TO-252) surface-mount package.
It offers a superior balance of low on-resistance ( Rds(on)cap R sub d s open paren o n close paren end-sub ) and total gate charge ( Qgcap Q sub g
