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…

PDF of 46.0 KB documenting the 2SB1409, a Japanese-registered transistor number; the name carries no further detail such as manufacturer or version.

The 2SB1406 transistor is the subject of this 70.7 KB PDF, listed under schematics but best treated as a datasheet. No other information is encoded in the name.

PDF file of 231 KB for the 2SA1586, catalogued as a schematic but named after one discrete semiconductor.

Covering the 2SB1018A, this 233 KB PDF is indexed as a schematic but describes a single transistor.

For anyone replacing a 2SA1417, this 141 KB PDF gives the component reference in one document, though the index labels it a schematic.

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…

Covering the 2SA1837, this 173 KB PDF is listed as a schematic but is expected to be a transistor datasheet.

Datasheet for the 2SA1811 in PDF format, 173 KB in size, filed alongside schematics in the catalogue.

Datasheet PDF of 190 KB for the 2SA1761, filed under the schematic type. In the JIS scheme the 2SA prefix denotes a PNP bipolar transistor, and the name gives nothing…

Component documentation for the 2N7222, a 227 KB PDF filed under schematics; the 2N prefix indicates a registered discrete semiconductor, so expect a datasheet rather…

A 171 KB PDF catalogued as a schematic for the 2N6379, with an RE suffix not defined by the file name.

Reference data for the 1T417 transistor in a 47.5 KB PDF, filed in the schematic section. The 1T prefix marks a germanium transistor in the old Soviet naming system.

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 1N4937GP diode, 45.7 KB PDF, indexed as a schematic. The GP suffix is typically used by manufacturers for glass-passivated construction.

Listed as a schematic, the 229 KB PDF titled 1B21 carries only a short code and no model, brand or revision, so its subject must be confirmed by opening it.

PDF datasheet, 425 KB, for the 93C45A serial EEPROM within the 93-series three-wire Microwire family, filed in the schematic category.

Combined datasheet in PDF covering the 93C06 and 93C46 serial EEPROMs, small low-density Microwire memories from the 93-series family, 135 KB in size.

Listed as a schematic, this 87.9 KB PDF carries the code 72cpq030 and nothing else: no brand, laptop model or board revision.

A short PDF of 53.5 KB, labelled 60CDQ and catalogued as a schematic. No product, brand, board revision or version appears in the name, so it should be opened in a…

PDF of 697 KB labelled 25C04 and catalogued among schematics. The naming corresponds to a 4 Kbit SPI serial EEPROM of the 25 family; no manufacturer, laptop or board is…

Here the name gives only the part number 12CWQ03FN, and at 129 KB the PDF is almost certainly a single component datasheet.

A 199 KB PDF for the 8ETH03 part, listed as a schematic in the index. The name fits the International Rectifier and Vishay hyperfast rectifier coding, so expect a…

PDF schematic labelled SL410, 1.32 MB, with no brand, motherboard number or revision in the file name.

RAR archive labelled H0222-2, 427 KB in size, without any brand, model or document type in its name.

Compressed package, 1.24 MB, named 3D1 with the number 20, which may be a revision indicator.
