The 2SC4250 transistor is documented in this 347 KB PDF, listed among schematics in the index.

At 214 KB, this PDF named 2SC4118 is filed as a schematic but is most plausibly a fuller datasheet for that part, likely with characteristic curves.

Short 125 KB PDF on the 2SC5086FT, the FT-suffixed variant of the 2SC5086 NPN transistor; the name does not say what the suffix means, though such suffixes usually mark…

The 2SC4071 is the subject of this 47.7 KB PDF, which sits in the schematic category although the name suggests a single-component datasheet.

The 2SC4030 transistor is documented in this 119 KB PDF, which is listed in the schematic section.

An 86.0 KB PDF carrying the part number 2SC3998, catalogued as a schematic but by name a single-device datasheet.

Part documentation for the 2SC5026 in PDF form, 41.3 KB, its name ending in an _E suffix.

The name of this 176 KB PDF consists only of 2SC3790, a JIS-style part number in which 2SC denotes an NPN transistor.

Reference sheet for the 2SC5363 transistor, delivered as a compact 40.7 KB PDF and listed among schematics.

The 2SC3747 transistor is covered by this 95.9 KB PDF, categorised as a schematic but by its name a datasheet for a single component.

Compact 91.1 KB PDF datasheet for the 2SC3595 transistor, listed in the schematic category.

Part number 2SC2911 is all the 43.6 KB PDF name states, and the index lists it as a schematic.

A 45.3 KB PDF titled with the JIS transistor number 2SC2909, filed under the schematic category.

Brief 21.6 KB PDF for the 2SC1815 with a UTC tag in the name, which refers to Unisonic Technologies as the issuing manufacturer.

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 documentation for the 2SA1591, an 89.4 KB PDF. Only the part number appears in the name; no revision or manufacturer is given.

A compact 19.1 KB PDF for the 2SA1580, small enough that it is probably a one- or two-page summary sheet. No other details are present in the name.

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.

A 39.8 KB PDF filed under schematics that covers the 2SB835 transistor, with an _E suffix in the name whose meaning is not stated and may simply denote an edition or…

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 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…

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.

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…

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 file is a 56.2 KB PDF listed under schematics and labelled 1T408, with nothing else in the name to tie it to a specific product or board.

Named 1T405A, this 69.4 KB PDF is filed as a schematic. The A suffix marks a variant of the 1T405 code, and the two should not be assumed interchangeable.

Part code 1SV234 is the only detail in the name of this 65.8 KB PDF, which is filed as a schematic. No equipment model or board number is stated.

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

Only the part number 1SS374 is given in the name of this 68.5 KB PDF, so treat it as a component specification rather than a board schematic.

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

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.

Component datasheet for the 1N457, a JEDEC 1N-series diode, saved as a 62.5 KB PDF and categorised here as a schematic.
