A 43.9 KB PDF for the 2SD2580, indexed as a schematic. Japanese JIS numbering reserves the 2SD prefix for NPN bipolar transistors in low-frequency applications, so this…

Listed as a schematic, this 89.6 KB PDF is named 2SD1883 and is most likely the corresponding transistor datasheet rather than a circuit drawing.

Compact 25.2 KB PDF named for the 3SK301, categorised as a schematic but most likely a part datasheet. Nothing besides the type number appears in the name.

PDF of 109 KB listed under schematics and named after the 2SK1441 part. The 2SK prefix places it in the JIS family of N-channel field-effect transistors, so the contents…

Part reference for the 2SK1259, a 37.4 KB PDF covering an N-channel FET in the Japanese 2SK series.

Component documentation for the 2SC5279 in a 124 KB PDF. Under Japanese naming, 2SC means an NPN bipolar transistor, so the content is expected to be a datasheet rather…

Compact 52.7 KB PDF for the 2SC4731, indexed as a schematic though its name identifies a single semiconductor.

Lower-case filename for the 2sc4726, a 60.4 KB PDF listed as a schematic. The number fits the Japanese JIS pattern where 2SC designates an NPN bipolar transistor, so…

Brief 68.6 KB PDF bearing the number 2SC4681, placed under schematics. The 2SC prefix is JIS shorthand for an NPN bipolar transistor, so treat the file as the part…

The smallest of this group at 71.8 KB, this PDF is named for the 2SC5250 NPN transistor and is likely a concise datasheet despite its schematic category.

For the 2SC4631 transistor, the index holds this 97.9 KB PDF, categorised as a schematic but evidently a component datasheet.

Datasheet-type PDF of 132 KB covering transistor 2SC4438, filed with the schematics in this index.

Covering the 2SC4306, this 100 KB PDF is indexed as a schematic, but with no board or device named it is best treated as the transistor datasheet.

At 188 KB, this PDF for the 2SC5466 is larger than a basic sheet and likely includes full characteristic curves and package drawings.

This 216 KB PDF documents the 2SC5463, a 2SC-series part, which under Japanese JIS designation is an NPN bipolar transistor.

The 220 KB PDF named 2SC5076 is classed as a schematic, yet the name is simply a JIS part number for an NPN transistor, making it most likely a datasheet.

This 125 KB PDF refers to 2SC5066FT, an NPN transistor in the Japanese 2SC numbering; the FT suffix most likely denotes a package or variant code, which the document…

Part number 2SC4840 names this 468 KB PDF, which the index lists as a schematic. Following JIS conventions, the 2SC prefix marks an NPN transistor, so expect datasheet…

Component datasheet covering the 2SC3750, a JIS-designated NPN bipolar transistor, saved as a 101 KB PDF in the schematic category.

Filed among schematics, this 118 KB PDF is identified solely by 2SC3451, a Japanese JIS transistor number.

The name of this 238 KB PDF consists solely of 2SC3425, a JIS designation for an NPN bipolar transistor.

Part code 2SC3422 is the only clue in this 176 KB PDF filed as a schematic. The 2SC series in the Japanese JIS system covers NPN bipolar transistors, making a component…

File for the 2SC2703, a 173 KB PDF listed under schematics, whose name only states the part number.

A 94.5 KB PDF for the 2SA1471, listed under schematics though the name indicates a single transistor data sheet. In JIS designation, 2SA stands for a PNP transistor.

The 2SA1435 is the subject of this 29.8 KB PDF, and the file name gives nothing beyond the part number.

Component datasheet for the 2SA2061 transistor, provided as a PDF of about 169 KB and listed under schematics.

Transistor datasheet candidate for 2SA2012, supplied as a 49.6 KB PDF. The 2SA prefix in JIS naming stands for a PNP bipolar transistor; the name gives nothing beyond…

Datasheet for the 2SA1801 transistor in PDF format, roughly 123 KB. JIS part numbering uses the 2SA prefix for PNP bipolar transistors, so the sheet should contain…

Listed as a schematic, a 147 KB PDF titled with the JEDEC code 2N6760 and nothing more. No equipment model or board information is provided.

A 200 KB PDF on the 2N3905, distinguished by an RE suffix that the name leaves unexplained, possibly an alternate or revised vendor edition.

PDF documentation for the 1SV282, 74.2 KB, stored in the schematics section. The 1SV numbering denotes a varactor diode, so rather than a board layout the file likely…

This 260 KB PDF labelled 1B51 is catalogued as a schematic, though the short code more likely names a discrete component and the file is probably its datasheet.

Labelled 80CPTN015, this 70.0 KB PDF is classed as a schematic yet carries a semiconductor part code rather than a board number, resembling International Rectifier…

PDF of 674 KB named 25C01, catalogued among schematics, with no manufacturer, laptop or board identified.
