PDF datasheet material for the 2SD1194 transistor, about 138 KB, catalogued here under schematics.

Component sheet for the 2SC4615 NPN transistor, around 154 KB in PDF format and filed as a schematic.

Indexed as a schematic, this 101 KB PDF is named for the semiconductor 2SC4441. The 2SC portion is a JIS designation for NPN bipolar transistors of the high-frequency…

The 2SC4423 is described by this 102 KB PDF, which the index lists as a schematic. Since 2SC is the JIS prefix for NPN bipolar transistors, the contents should be a…

Indexed as a schematic, this 105 KB PDF actually carries a semiconductor part number, 2SC4406.

Datasheet-style PDF of 158 KB for the 2SC5765, indexed in the schematics section. Beyond the part number the name is uninformative; the 2SC prefix denotes an NPN…

The 2SC3951 PDF, 41.1 KB, is indexed as a schematic but is named purely after a JIS transistor part, so treat it as a datasheet for an NPN bipolar device.

PDF for the 2SC5417LS, 43.1 KB, catalogued as a schematic. The LS letters after the number mark a variant of the base 2SC5417, which has its own sheet; compare both…

A 149 KB PDF carrying the bare transistor number 2SC4837. Though placed in the schematic category, the JIS prefix 2SC identifies an NPN transistor, so the file is…

Datasheet-style document for the 2SC3778 NPN transistor, stored as a 126 KB PDF under the schematic label.

A 320 KB PDF named for the 2SC3329, listed under schematics though it is most probably a full transistor datasheet.

The 330 KB PDF here carries the part number 2SC2551, a JIS-registered NPN transistor designation.

Reference PDF for the 2SB1438 transistor, about 44 KB, carrying an _E suffix that most likely marks the English version, and listed among schematics although it reads as…

Part number 2SA1533 names this 51.3 KB PDF, with an unexplained _E suffix; despite the schematic category it is presumably the transistor datasheet.

Datasheet for the 2SA1289, presented as a 40.7 KB PDF and listed in the schematic category. Nothing beyond the part code is given by the name.

Datasheet-type PDF for the 2SA1939, roughly 170 KB, catalogued here as a schematic. The filename names only the component; the JIS 2SA prefix marks it as a PNP bipolar…

Compact 45.3 KB PDF for the 2SA1207, listed as a schematic, though the name offers only the part number, which suggests a datasheet.

PDF documentation of the 1SV307 diode, about 69 KB and listed as a schematic. The part number follows the JIS 1SV pattern, which Toshiba uses for variable-capacitance…

Named after the code 129NQ135 and filed as a schematic, this 113 KB PDF gives no laptop model, board number or revision.

The 154 KB file 93CXXXX.pdf is indexed as a schematic, but the wildcard name points to a datasheet covering a range of 93C-series Microwire serial EEPROMs.

The 155 KB PDF titled 15tq060 is listed under schematics, but the name corresponds to the International Rectifier and Vishay Schottky rectifier numbering style.
