Schematic archive named only M33, with no brand given, a 940 KB ZIP. The name is too brief to identify the device reliably; it may be a phone model code, but that is not…

Compact 42.5 KB PDF for the 2SD1824, carrying an E suffix in the name that is not otherwise explained.

Data for the 2SD2184, an NPN low-frequency bipolar transistor according to the Japanese 2SD numbering prefix, supplied as a 43.8 KB PDF.

A 43.8 KB PDF for the 2SD2565 transistor, its name ending in _E. Although classified as a schematic, the file is most likely a datasheet, as the JIS prefix 2SD…

Revision 5 of a datasheet for the 4N25 optocoupler, a 281 KB PDF. The 4N25 is one of the oldest and most common phototransistor-output isolators, often found in power…

At 242 KB, the 2SD2092 PDF is one of the larger files in this series and carries no information beyond the part number.

The only detail in this 183 KB PDF name is the part number 2SD2461, indicating the datasheet for that transistor.

Datasheet-style document, 133 KB in PDF format, covering the 2SD1681 part number and listed as a schematic.

A compact 30.6 KB PDF tied to the 2SD1666 part number, catalogued among schematics. In Japanese JIS designations, 2SD stands for an NPN bipolar transistor meant for…

Larger 185 KB PDF for the 2SD2012, written in lowercase in the name and placed among schematics.

Very small 22.2 KB PDF relating to the 2SD1999, filed as a schematic. The name offers nothing but the part code, which follows the JIS scheme where 2SD denotes an NPN…

An 88.2 KB PDF titled 2SD1884, indexed in the schematic section but, judging by the bare part number, a datasheet for that transistor.

PDF documentation, 32.7 KB, for the 3SK269, indexed under schematics. The JIS code 3SK marks an N-channel field-effect transistor with four terminals, generally a…

The 3LP02SP part is documented in this 41.9 KB PDF, catalogued under schematics. The name gives only the component code; companion files 3LP02N and 3LP02M share the…

Reference document for the 2SK2679, a 393 KB PDF in the schematic category. The 2SK prefix is the Japanese JIS registration for N-channel field-effect transistors, so…

Component datasheet for the 2SK2661, a 385 KB PDF that is indexed as a schematic. Under JIS naming, the 2SK prefix marks an N-channel field-effect transistor, so look…

A 30.5 KB PDF for the 2SK2631, filed among schematics though the number is a JIS N-channel FET designation, meaning the content is a component datasheet.

PDF reference document of 413 KB for the 2SK2508 transistor, filed as a schematic. In JIS naming the 2SK prefix identifies an N-channel field-effect transistor; the name…

The 2SK2129, a JIS-registered N-channel FET, is the only thing the name identifies in this 32 KB PDF.

A 166 KB PDF covering the 2SK1961 transistor. The 2SK series in the JIS system denotes N-channel FETs, so this schematic-categorised file should be read as a component…

Largest of this group at 382 KB, this PDF documents the 2SK1930, an N-channel field-effect transistor under Japanese JIS numbering.

Only the part number 2SK1897 identifies this 97.1 KB PDF, which the index places among schematics.

PDF reference, 105 KB, for the 2SK1813 transistor. In the Japanese JIS scheme, 2SK designates an N-channel field-effect transistor, so this is probably its datasheet.
