Identified only as 2SK2169, this 88.2 KB PDF sits in the schematic category but is most likely a component datasheet. Under JIS/EIAJ rules the 2SK prefix denotes an N-channel field-effect transistor; the name does not reveal maker, package or ratings. Open it to find which lead is gate, drain or source, along with the absolute maximum figures. These are needed before testing with a meter in diode mode or ordering a cross-referenced replacement part.
