Named after the 2SC1383, this 51.4 KB PDF is listed as a schematic, yet the JIS prefix 2SC denotes an NPN bipolar transistor, so expect a part datasheet.

A 58.1 KB PDF labelled as a schematic and named after the 2SC1215, an NPN transistor by Japanese JIS naming, so it should be the datasheet for that discrete part.

Component datasheet for the 2sb1580, 64.2 KB in PDF and indexed as a schematic. The 2SB prefix comes from the JIS standard and indicates a PNP bipolar transistor for…

Datasheet for the 2SB1539 PNP transistor as a 40 KB PDF; the _E suffix most likely marks the English edition of the document.

Filed as a schematic, the 51.8 KB PDF for the 2SA1534 carries an _E suffix in its name whose meaning is not stated; the content is most likely the datasheet for this JIS…

The 2SA1518 is the subject of this 30.2 KB PDF, which the index files as a schematic although the name suggests a component data sheet.

PDF of 41.0 KB for the 2SB873, with an _E suffix whose meaning the name does not explain.

Reference sheet for the 2SA1300 transistor, supplied as a 207 KB PDF and filed under schematics in this index.

An 86 KB PDF covering the 2SA1896, a PNP bipolar transistor under the Japanese JIS 2SA designation.

The 2SA1869 is covered by this 174 KB PDF, a PNP bipolar transistor in the Japanese JIS 2SA series.

Short 31.2 KB PDF for the 2SA1864, a PNP bipolar transistor in the Japanese JIS 2SA family.

Small 81.5 KB PDF named after the 2SA1724 part number and filed under schematics. Nothing else in the name identifies a product or circuit board.

Small PDF listed as a schematic, though the name 2SA777 with suffix E reads like a discrete semiconductor part number in the Japanese 2SA style rather than a board…

PDF of 310 KB, the largest in this group, named 2N1893 and filed as a schematic. The JEDEC 2N designation indicates a discrete semiconductor, so the content is probably…

PDF reference of 51.6 KB named 2N1613, placed in the schematic category. The 2N prefix follows the JEDEC numbering used for discrete semiconductors, so the content is…

A 52.2 KB PDF in the schematic listing, labelled simply 2N6487, a part number from the JEDEC 2N discrete semiconductor series.

Filed as a schematic, this 271 KB PDF is named after the discrete part number 2N5684 with an unexplained RE suffix, which may indicate a reissued edition.

A 272 KB PDF for part number 2N5555, with a rev0x tag in the name that seems to mark a document revision, though its exact meaning is not stated.

Small 20.5 KB PDF named for 2N5551 with a UTC tag, which most likely refers to the manufacturer that published this version.

Part number 2N5551 is the sole identifier of this 74.3 KB PDF, listed as a schematic. Under the JEDEC 2N scheme the file is most plausibly a datasheet for the discrete…

Component datasheet in PDF form for the 2N5458, an N-channel junction FET usually found in TO-92 packages, catalogued here as a schematic-type document of about 130 KB.

Another copy of the 2N5401 datasheet, a 49.2 KB PDF whose _3 suffix probably marks an alternate version or a third saved copy rather than a documented revision.

Datasheet PDF of 204 KB for the 2N3771, a JEDEC 2N-series transistor, catalogued in the schematic section.

Part number 1T409 is the only information in the name of this 49.5 KB PDF, which is catalogued as a schematic.

The part code 1SV229 is all this 69.4 KB schematic-category PDF carries in its name, apart from a trailing underscore. No equipment or board information is present.

The 1SS190 is the only information in this file name, apart from an underscore. The 68.1 KB PDF sits under the schematic category.

Switching-diode reference named 1SS184, saved as a 69.3 KB PDF and filed by the index as a schematic. The underscore in the name carries no extra detail.

The 1SS398 is the subject of this 78.2 KB PDF, which is catalogued as a schematic but is likely a single-part datasheet.

Part number 1SS345 is the only information in this 58.3 KB PDF name, so no laptop, board or revision is identified.

Labelled 1SS268, this 126 KB PDF appears to be a datasheet for a single component even though the index lists it as a schematic.

Part number 1SS196 gives this 68.1 KB PDF its name, which marks it as a datasheet for a single semiconductor rather than a full circuit diagram.

The 1N486B is the subject of this 33.1 KB PDF, a datasheet for a JEDEC 1N-series diode even though it carries the schematic label.

A 42.7 KB PDF datasheet for the 1N5391 diode, listed here as a schematic although it covers a single component.

Datasheet for the 1N5059 diode as a 52.4 KB PDF, filed in the schematic category though it is a part specification sheet.

PDF datasheet, 45.5 KB, for the 1N4934 fast recovery rectifier diode from the 1N4933 to 1N4937 family.
