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…

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.

Datasheet for the 1T412 transistor, 59.8 KB in PDF format and stored with schematics. The 1T prefix places it among Soviet germanium transistors.

Datasheet for the 2SD2223, in PDF form at 133 KB and indexed as a schematic. The name identifies only this transistor type.

A 195 KB PDF labelled with the transistor type 2SC4210. No device, board or manufacturer is named; the 2SC prefix simply tells us, through the Japanese JEITA system…

Reference PDF of 176 KB for the 2SA1425 transistor, carrying no information in its name beyond the part number.

PDF of about 113 KB identified by the transistor number 2SC4403. The JIS prefix 2SC marks an NPN bipolar transistor, so this document should provide datasheet…

PDF reference sheet for the 2sb1236 transistor, 52.0 KB. The file name carries the part number only, with no further detail.

Reference sheet for the 2SA719 transistor, delivered as a 51.3 KB PDF carrying an unexplained _E suffix.

At 138 KB, this PDF is named for the 2SC4414 and stored under schematics, though the name is a transistor part number.

A 185 KB PDF for the 2SC5331 transistor, indexed as a schematic although the part-number title points to a datasheet.

The 2SB906 transistor is the subject of this 196 KB PDF. Following JIS designation, 2SB parts are PNP bipolar transistors classed for low-frequency use.

A 59.2 KB PDF describing the 2sb1275 transistor, filed as a schematic though the name points to a single part.

This 30.5 KB PDF is titled with the 2SA1526 part number and indexed as a schematic, though it is most likely the transistor's datasheet.

Datasheet PDF, 81.8 KB, for the 2SC3997 transistor, placed in the schematic listing. JIS numbering uses 2SC for NPN bipolar transistors; nothing else, such as maker or…

Named only 2sd1897, this 35.6 KB PDF is listed as a schematic, yet the name is a JIS transistor number, so it is very likely a compact datasheet.

Datasheet-type PDF for the MJE13009, a high-voltage NPN power transistor, catalogued under schematics. The name carries only the part number.
