Reference sheet in PDF format for the 2SC4256, 80.8 KB in size. The file name gives no manufacturer, package or revision details.

Part number 2SC4223 is all the file name gives, so this 93.9 KB PDF is best treated as a datasheet for that component rather than a circuit schematic.

Filed in the schematic section, this 156 KB PDF is named for the 2SC4135, which by JIS convention is an NPN bipolar transistor, so expect a component datasheet inside.

The 2SC5526 is documented in this 52.6 KB PDF, placed among schematics in the index. By Japanese JIS convention a 2SC part is an NPN bipolar transistor, so the file…

At 168 KB, the document covers part 2SC5692 and is filed as a schematic. The 2SC prefix follows the Japanese JIS convention for NPN transistors intended for…

Component datasheet for the 2SC4868, provided as a 123 KB PDF and filed as a schematic. The name states only the part number.

PDF documentation for the 2SC4793 transistor, at 173 KB larger than most files in this series and probably a fuller datasheet with characteristic curves.

Only the part number 2SC3361 appears in the name of this 129 KB PDF, so no equipment or board can be identified from it.

Datasheet-style PDF named for the 2SC5322, 122 KB, though the catalogue labels it a schematic.

Datasheet-style PDF, 96.2 KB, named only for the 2SC3089 and catalogued as a schematic.

The 2SB1674 named here is, under JIS conventions, a PNP bipolar transistor; this 52.6 KB PDF, despite its schematic category, is therefore most likely the datasheet.

Datasheet in PDF format for the 2SB1641, around 183 KB. By JIS convention the 2SB prefix identifies a PNP bipolar transistor aimed at low-frequency circuits such as…

The 2SB1557 PNP transistor datasheet, a 184 KB PDF catalogued as a schematic. By JIS convention the 2SB prefix identifies PNP bipolar transistors for low-frequency use…

The name points to the 2SB1219 transistor, and this 43.6 KB PDF with an _E suffix, though filed as a schematic, should be its datasheet.

The 2SB857 transistor is covered in this 42.0 KB PDF, the same size as the 2SB858 file and probably from the same document series.

PDF datasheet for the 2SA1338, a part whose 2SA prefix marks it as a PNP transistor intended for high-frequency service under the Japanese JIS convention.

Combined PDF datasheet for the 1N5820, 1N5821 and 1N5822 Schottky rectifiers, 3 A parts rated at 20, 30 and 40 V respectively.

Listed as a schematic, this 138 KB PDF is titled with a part range from 1PMT5913BT3 to 48BT3, the naming style of a Zener diode series in a compact surface-mount power…

A 144 KB PDF named 23c020, describing a component in the 23C series, which by usual convention are mask-programmed ROMs; 020 normally corresponds to 2 Mbit.

English-language PDF about DC-to-DC regulators, 3.13 MB, filed with schematics. The name carries a numeric code but no specific IC or board, so it reads as a general…

Small 120 KB PDF that, judging by its Persian title, is a saved Wikipedia encyclopedia article about inverters rather than a board-level schematic.

Schematic in PDF form for the HP TouchSmart TX2 convertible, covering the Quanta-built mainboard numbered DA0TT3MB8D0 with the TT3 project code.

Covering the 2SD1817, this 75.8 KB PDF is indexed as a schematic but by name is a component datasheet. No maker or revision is indicated.

At just 33.5 KB, this PDF for the 2SD1623 is a short document listed as a schematic, though the part-number name suggests a compact datasheet.

Listed as a schematic, this 412 KB PDF carries only the part number 2SK2845 in its name.

For the 2SK2744 this 177 KB PDF provides component-level reference material, although the index lists it among schematics.

Part reference for the 2SK2607, an N-channel FET according to the 2SK prefix of the JIS numbering convention.

Covering the 2sk2580, this 34.5 KB PDF is labelled a schematic yet identifies only a semiconductor part, pointing to a short datasheet.

Component document for the 2SC5000, a 179 KB PDF placed among schematics. The file name gives nothing besides the part number.

The 2SA1298 is covered by this 203 KB PDF, catalogued as a schematic but named only after the component.

Component sheet for the 2SA1866 PNP bipolar transistor, stored as a 55.4 KB PDF. The 2SA prefix follows Japanese JIS conventions for PNP devices.

PDF of 210 KB for the 2SA817 transistor, catalogued as a schematic but named only by the component number.

Filed as a schematic, this 69.5 KB PDF carries the part number 1SS226 and is best read as a component datasheet.

A 72.5 KB PDF for the 6F(R) series, a rectifier diode family where the R variant conventionally indicates reverse polarity, with the stud or case as anode instead of…

PDF of 329 KB named 25C040, indexed as a schematic although the name points to a 25-series SPI serial EEPROM, where 040 conventionally denotes 4 Kbit capacity.

Schematic of the GE3A power supply and inverter board in the Sony KDL-40NX705 television, version AZ1-H, as a 2.18 MB PDF.

Schematic PDF for the Sony board numbered 1-689-604-12, 1.30 MB. Part references in the name are PQ12DZ5UJ00H, UC3854BN and MCZ3001D, pointing to a power supply design.
