Datasheet-style PDF for the 2SK2126, around 34 KB, indexed as a schematic. The JIS prefix 2SK marks it as an N-channel field-effect transistor, and the name says nothing about its maker or package. Use it when identifying gate, drain and source to measure the part out of circuit, or when checking that a replacement has a suitable voltage rating, current capacity and threshold. It sits alongside other 2SK212x files with similar small sizes.
