NTMFS4946N datasheet from ON Semiconductor, 172 KB PDF, describing an N-channel power MOSFET in the SO-8FL flat package. Parts from this family are common in notebook voltage regulators, and a failed one often shows as a shorted rail. The document provides the pin layout for probing, along with breakdown voltage, current capability and on-resistance to compare against a replacement. Read the device marking on the board first and match it to the marking information in the sheet, since related part numbers are not equivalent.
