Component documentation for the 2SD2257 transistor, in PDF form at 180 KB. Although the index lists it as a schematic, the file name points to a single discrete part…

Datasheet-type PDF, 30.8 KB, for the 2SD2627LS, catalogued as a schematic. The LS suffix is part of the type designation and likely refers to a specific variant or…

The 2SD2079 PDF, 219 KB in size, is indexed as a schematic yet corresponds to a single discrete component.

At 198 KB, the PDF for the 2SD1658 is one of the larger sheets in this group, though it still names only the part.

Component documentation for the 2SD1881 transistor, supplied as a 90.6 KB PDF and catalogued as a schematic, though a part number like this normally points to a…

Compact 43.6 KB PDF named for the 3N249 and filed as a schematic, although it is almost certainly a component datasheet.

The 2SK3413LS is documented in this compact 32.2 KB PDF, indexed as a schematic but effectively a component datasheet.

Datasheet-style PDF for the 2SK3018, indexed here under schematics, though the 2SK prefix marks a Japanese JIS-registered N-channel field-effect transistor rather than a…

Brief PDF, about 30.2 KB, for the 2SK2509, a JIS-designated N-channel FET as indicated by its 2SK prefix.

Filed under schematics, this 138 KB PDF is named after the 2SK2463, a JIS-style part number, so it is most likely a component datasheet rather than a board drawing.

Document for the 2SK2400, 403 KB in PDF format and listed as a schematic, although the name points to a single-component datasheet.

Component documentation in a 114 KB PDF for the 2SK2011. Parts with the 2SK prefix are N-channel field-effect transistors under the Japanese numbering standard, so this…

The 2SK1920 is the only detail in this file name, and the 93.1 KB PDF is indexed as a schematic.

Part 2SK1890, documented in a 96.7 KB PDF placed in the schematic category. Japanese JIS numbering reserves 2SK for N-channel FETs, so this is a component datasheet…

For the 2SK1470, a Japanese-coded N-channel field-effect transistor, this 97.9 KB PDF serves as component reference material even though it sits in the schematic…

Reference PDF for the 2SK1382 N-channel MOSFET, 389 KB, listed in the schematic category of the index.

Covering the 2SJ589LS, this 33.2 KB PDF is catalogued as a schematic, though the name points to a component datasheet.

This 93.0 KB PDF carries the part number 2SJ258 and nothing else. The 2SJ prefix, under Japanese JIS numbering, indicates a P-channel field-effect transistor, so expect…

Named only 2SJ232, this 88.9 KB PDF relates to a P-channel field-effect transistor, as indicated by the JIS 2SJ prefix.

Listed in the schematic category, this small 105 KB PDF is in practice a component document for the 2SD1064 part.

A 155 KB PDF bearing the part number 2SC4734 and nothing else. The 2SC prefix belongs to the JIS/JEITA system for NPN bipolar transistors, so despite the schematic label…
