Listed as a schematic, this 89.6 KB PDF is named 2SD1883 and is most likely the corresponding transistor datasheet rather than a circuit drawing.

A 122 KB datasheet-style PDF for the 2SD1012, indexed as a schematic. The name gives only the part number, which belongs to the JIS 2SD family of NPN bipolar transistors…

Compact 52.7 KB PDF for the 2SC4731, indexed as a schematic though its name identifies a single semiconductor.

Datasheet for the 2SC4480, stored as a 99.8 KB PDF that opens in any standard reader. By JIS convention the 2SC prefix denotes an NPN bipolar transistor; the name gives…

The 182 KB PDF bears the name 2SC5712, a JIS designation pointing to an NPN bipolar transistor, so it is presumably a datasheet despite the schematic label.

The 2SC3676 transistor is covered in this 96.8 KB PDF, which the index files as a schematic.

A 176 KB PDF bearing only the JIS transistor number 2SC3421, categorised as a schematic but most likely a datasheet. The 2SC prefix denotes an NPN bipolar transistor.

Only the part number 2SC3332 appears in the name of this 115 KB PDF, which is labelled a schematic but is most likely a transistor datasheet.

A 205 KB PDF bearing only the part number 2SC2710, catalogued as a schematic but most likely a component datasheet.

The code 80EBU04 on this 147 KB PDF matches International Rectifier style naming for a rectifier diode, so although it sits in the schematic category, a component…

Tone control circuit intended for a 2.1 channel audio system, in a 159 KB PDF. It shows the bass and treble adjustment network that sits between the source or preamp and…

Schematic of a 2.1 channel amplifier based on the TDA2030A, from Technical Mriganka, in a 416 KB PDF.

Schematic in PDF form, 2.03 MB, for a subwoofer identified in the name as e150p. No manufacturer or board revision is stated, so confirm the model label on the enclosure…

Power board schematic for Samsung BN44-00438A, provided as a 637 KB PDF. BN44 numbers mark Samsung TV power supply units, and revision A should match the sticker on the…

Covers the 2SD2195, a part whose JIS-style 2SD prefix identifies it as an NPN bipolar transistor rated for low-frequency work.

The 2SD1622 PDF, 138 KB in size, sits among schematics, but a file named only by a semiconductor part number is very likely the device datasheet.

Datasheet-style PDF, 137 KB, covering the 2SK2550 transistor even though the catalogue lists it as a schematic.

Covers the 2SK1725 transistor in an 85.8 KB PDF, indexed among schematics but in practice a single-component datasheet.

Slightly larger at 109 KB, this PDF covers the 2SK1419 and is listed among schematics, though it most likely holds a datasheet.
