Datasheet PDF, 392 KB, for the 2SK2992. The 2SK prefix belongs to the Japanese JIS registration for N-channel FETs, so despite the schematic category this describes one discrete component. Repair technicians consult such documents to identify gate, drain and source, read characteristic curves and confirm maximum voltage before substituting a part in power supplies or motor drivers. Match the exact suffix and package on the failed component before ordering, since variants can differ.
