A 29.5 KB PDF referencing the 2SC5792 transistor, an NPN device in the JIS-registered 2SC range.

Filed as a schematic at 106 KB, this PDF bears only the identifier 2SC5070. That code belongs to the Japanese 2SC series of NPN transistors, so the document should be a…

The 2SA1587 transistor is the subject of this 323 KB PDF, the largest in this group and likely to include detailed characteristic graphs.

Data sheet style PDF, 95.9 KB, named for the 2SA1470 and indexed as a schematic. The 2SA prefix under the Japanese JIS scheme identifies a PNP bipolar transistor.

A 127 KB PDF on the 2SA1450, listed among schematics though the name refers to a single semiconductor.

Named 2n6439 with rev0 appended, this 127 KB PDF is filed as a schematic and appears to be revision 0 of a document for that JEDEC 2N-series discrete semiconductor.

Listed as a schematic, a 115 KB PDF carrying only the part number 2N6342, part of the JEDEC 2N registration series for discrete semiconductors.

Reference PDF of 96.5 KB tied to the 2N6237, a JEDEC-numbered discrete semiconductor; the index lists it as a schematic, but it most likely holds the device datasheet.

PDF datasheet of 136 KB for the 2N3442, catalogued under schematics; the RE suffix in the name is not explained and may identify a revised copy.

Family datasheet covering the 1N5283 through 1N5314 range, 84.4 KB PDF, filed in the schematic category.

Specification sheet for the 1N5283, saved as a 119 KB PDF and indexed as a schematic. Its size matches the 1N5292 file, which hints that both are the same series…

Named simply 1N821, this 34.4 KB PDF follows JEDEC 1N diode numbering and is most likely a single-part datasheet, not a circuit diagram, even though it sits in the…

A 305 KB PDF with the short code 1B41, indexed as a schematic; the name gives no model or board, and it may be a component datasheet in a numbered series alongside 1B51…

Indexed under schematics, this 181 KB PDF named 28512 most likely documents a 28-series 512 Kbit parallel EEPROM, though the name does not confirm the manufacturer or…

This 89.3 KB PDF, classified as a schematic, is named 27128 and carries no brand, device or board details.

PDF of 97.8 KB for the 40EPF-HV, filed as a schematic though it is component documentation.

Catalogued as a schematic, this 140 KB PDF carries the name 28F002, a part code from the 28F flash memory series, typically a 2 Mbit boot block type.

A 92.7 KB PDF catalogued as a schematic, named 28C257, a code from the 28C series of parallel EEPROM memories. The name gives no vendor, speed grade or package.
