Does anyone have the name of this manufacturer? These parts are probably MOSFETs from their usage, but the logo in not familiar to me.

I thought that the number "4407" indicated the date code, but you may be correct about it being the part number. Also, searching for a datasheet for a BE4C4L yields nothing.

 

Yes, 4407 is the part number - I just looked at how A&O marks their parts.
