The name carries only the part number 2SK2127, an N-channel FET designation in the Japanese JIS system. This is a 32 KB PDF listed under schematics but probably a datasheet. The manufacturer is not given, so confirm it from the package marking on the board. The sheet is useful for pinout, absolute ratings and switching characteristics. Read them before swapping in a different MOSFET, because a lower voltage rating or higher on-resistance can cause repeat failures.
