Indexed as a schematic, this 129 KB PDF concerns the 2SK2095N, where the N may mark a variant of the base 2SK2095 part. Like other 2SK devices it is a JIS-registered N-channel FET, and the file is most likely its datasheet. The 1-5 suffix is not explained by the name. A plain 2sk2095n copy of similar size is also catalogued. Use it to confirm pinout and ratings before replacing or substituting the transistor.
