Part sheet for the 2SK2698, delivered as a 413 KB PDF. Following JIS naming, 2SK parts are N-channel FETs, and the file size points to a complete datasheet with graphs rather than a one-page summary. Bench use is straightforward: identify drain, gate and source, test the device out of circuit, and compare ratings against possible replacements. Neighbouring numbers such as 2SK2699 may look similar but are separate parts, so match the exact code on the component body.
