Documentation for the 2SK2036 in a 326 KB PDF. Parts beginning with 2SK are N-channel field-effect transistors under the Japanese JIS numbering, so this file should be read as a datasheet even though the catalogue type says schematic. Repair work typically uses it to identify which leg is gate, drain and source, check voltage and current limits, and judge whether a proposed substitute is adequate. The file name carries no further details such as maker or package, so cross-check the physical part marking.
