Datasheet-style PDF, 55.1 KB, for the 2SK2347 semiconductor, stored in the schematic section of the index. In the Japanese JIS designation system 2SK identifies an N-channel field-effect transistor. Technicians reach for this kind of sheet when diagnosing a shorted switching stage, checking whether a tester reading makes sense, or selecting an equivalent with similar voltage, current and on-resistance. Nothing beyond the part number appears in the name, so confirm package and suffix against the physical component first.
