The 2SD1908 transistor is documented in this 85.8 KB PDF, which the index files as a schematic, although a JIS part number like this normally indicates a datasheet.

A 68.3 KB PDF bearing the name 2SD2324, a Japanese JIS designation for an NPN transistor, since 2SD marks NPN low-frequency devices.

Named only 2sd1897, this 35.6 KB PDF is listed as a schematic, yet the name is a JIS transistor number, so it is very likely a compact datasheet.

Reference sheet for the 2SK2917 N-channel field-effect transistor, stored as a 423 KB PDF and listed in the schematic category.

Indexed as a schematic, this 112 KB PDF carries just the name 2SK1454, a JIS-style code for an N-channel field-effect transistor.

Small 53.0 KB PDF for the 2SD1280 with an _E suffix, classified as a schematic in the index.
