Single-part PDF of 47.0 KB for the 2SD2583, listed as a schematic but most probably a datasheet.

Datasheet-style document for the 2SD2581 transistor, saved as a 43.7 KB PDF and filed in the schematic category.

Compact 42.8 KB PDF for the 2SD2537, listed as a schematic though the name points to a single-component datasheet.

A 41.4 KB PDF covering the 5HP02C part, indexed under schematics. Only the component code is present in the name, with C most likely denoting the package type.

Component documentation for the 4N38 optocoupler, filed under schematics though it is in practice a part datasheet in PDF form of about 140 KB.

The name offers nothing beyond the 2SD2500 part number, and the 250 KB PDF is almost certainly that transistor's datasheet.

The 2SD1683 is the subject of this 146 KB PDF, which is catalogued as a schematic although the name is a transistor part number.

Transistor documentation for the 2SD1667, 136 KB in PDF format. Nothing beyond the part number appears in the name.

PDF of 119 KB for the 2SD1664, written in lowercase in the original name and filed as a schematic.

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

Datasheet PDF, 60 KB, for the 2SD1650, with the name given in lowercase and filed under schematics.

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

Part number 2SD1424 with an unexplained _E suffix names this 41.4 KB PDF, indexed among schematics but most likely a datasheet for the transistor.

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…

PDF covering the 2SD1880, about 88.9 KB, listed as a schematic but named after a single semiconductor part.

Reference sheet for the 3SK180 semiconductor in PDF form, roughly 173 KB, catalogued as a schematic.

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

Part number 2SD2459 names this 41.2 KB PDF, followed by an unexplained E tag; it is catalogued as a schematic.

Catalogued as a schematic, the 40.9 KB PDF 2SD2413 with an E tag relates, by the JIS 2SD prefix, to an NPN bipolar transistor rather than a complete board.

PDF document for the 2SD1995 semiconductor, catalogued under schematics but by its name a component datasheet.

The 2SD1511 NPN transistor is the subject of this 56.9 KB PDF, filed under schematics in the index. JIS numbering assigns 2SD to low-frequency NPN bipolar parts.

The name carries only a part number, 2SD1905, which points to a semiconductor datasheet even though the entry is filed under schematics.

Tiny 30.2 KB PDF named 2sk65, a JIS part number that indicates a component datasheet, although it is filed as a schematic.

Datasheet-type PDF of 31.1 KB for the 2SK3412 semiconductor, stored under the schematic category.

Covering the 2SK3335, this small PDF (32.6 KB) is a part datasheet placed in the schematic category.

The 2SK3291 transistor is the subject of this 34.2 KB PDF, filed as a schematic although it works as a datasheet.

Here the 2SK3285 is documented in a 48.6 KB PDF, placed in the index's schematic section.

The name of this 421 KB PDF carries just one token, 2SK2836, a JIS-format number for an N-channel FET.

PDF reference for the 2SK2825, 301 KB in size and listed in the schematic section. The 2SK designation, from the Japanese JIS numbering system, belongs to N-channel…

Part reference for the 2SK2782, delivered as a 419 KB PDF under the schematic label. The 2SK prefix follows Japanese JIS numbering for N-channel field-effect…

PDF reference for the 2SK2749 transistor, 412 KB, stored in the schematic section. Under Japanese JIS numbering the 2SK prefix identifies an N-channel field-effect…

The 2SK2718 is documented in a 412 KB PDF that the catalogue files under schematics, though by its name it is a component datasheet.

Brief 34.7 KB PDF for the 2sk2581 transistor, catalogued as a schematic. JIS naming assigns 2SK to N-channel field-effect transistors, and the name gives no further…

Part document for the 2sk2575, 35.2 KB in PDF format and catalogued as a schematic. The 2SK prefix in JIS nomenclature marks an N-channel field-effect transistor; the…

Small 33.8 KB PDF on the 2sk2495, a part number in the JIS N-channel FET series marked by the 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.

Datasheet-style PDF, 55.1 KB, for the 2SK2347 semiconductor, stored in the schematic section of the index.
