Book in PDF form, about 7.88 MB, covering valve and transistor audio amplifiers; the tag in the name only reflects where the copy was sourced.

Peavey transistor cross-reference sheet in a compact 96.6 KB PDF. Peavey amplifiers often use in-house part numbers on semiconductors, and a cross list like this maps…

First part of a split RAR archive with a saved video explaining how a MOSFET transistor works.

Small Spanish PDF, 62.9 KB, numbered 121 in what looks like a circuit series, showing load switching with a relay driven by a transistor.

Another copy of the BUW84 and BUW85 NPN power transistor sheet, judging by the duplicate-style suffix in the name and the identical 101 KB size.

Datasheet in PDF for the PZT2907A, a PNP small-signal transistor the file name rates at 60 V.

Portuguese-language PDF listing complete equivalences for SMD transistors, a cross-reference for identifying surface-mount parts by their marking code and finding…

Cross-reference sheet listing equivalents for diodes, bridge rectifiers and transistors, originally prepared as an Excel table and saved to PDF, despite being filed here…

Datasheet for the BUW84 and BUW85 NPN power transistors, as stated in the name, in a 101 KB PDF indexed as a schematic.

PDF reference of 45.2 KB for the 1T363 transistor, filed in the schematic section. The designation follows the old Soviet system, where 1T stands for a germanium…

Final PCB artwork for an amplifier using Sanken output transistors, labelled 7 set, which likely indicates seven pairs of output devices, delivered as a large 7.42 MB…

Datasheet in PDF form for the 2SA1321 transistor, about 213 KB, filed in the schematic category.

An 87.4 KB PDF describing the 2SA1839 transistor, indexed with the schematic files. Following JIS numbering, the 2SA designation indicates a PNP bipolar transistor.

Covering the 2SD2578 transistor, this 45.0 KB PDF sits in the schematic category but is probably a manufacturer datasheet.

Here the 2SC5231 is covered by a 133 KB PDF that the catalogue files under schematics, although it most likely is a transistor datasheet.

Covering the 2SC3953 transistor, this 40.7 KB PDF is catalogued as a schematic, though a JIS part-number name like this normally denotes a datasheet.

Indexed as a schematic, this compact 30.5 KB PDF is named for the 2SA1529, a JIS transistor number, and is best read as that part's datasheet.

For the 2SA1783 transistor, a 186 KB PDF sits in the schematic category, though the JIS designation makes it a part datasheet rather than a circuit diagram.

Short 88.9 KB PDF carrying the transistor number 2SC4217, filed among schematics. JEITA assigns the 2SC prefix to NPN bipolar transistors, so this should be a datasheet…

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