PDF reference on the 2SC4517 transistor, the name noting it as NPN; the file is 26.9 KB and indexed as a schematic.

Catalogued as a schematic, this 27.2 KB PDF carries only the code 3LP01SS, which looks like a component part number with a two-letter SS suffix.

PDF reference of 221 KB for the 2SK2909, catalogued as a schematic. Only the part number is present in the name, with no maker or revision indicated.

The 2SC4163 part number is all this 98.9 KB PDF name reveals, so although labelled a schematic it is best read as a transistor datasheet.

At 192 KB this PDF is somewhat larger than its neighbours and covers the 2SC3142 transistor, an NPN bipolar part under JIS 2SC numbering.

Reference PDF for the 2SA1127 transistor, 41 KB, filed in the schematic category, with an _E suffix in the name whose meaning is not stated.

Listed as a schematic, this 68.8 KB document carries the name 1SS378 and nothing else, pointing to a component data sheet for a small-signal silicon diode under the JIS…

The name 243NQ gives only a part family prefix with no suffix, so this 45.4 KB PDF probably covers a whole series of power rectifier devices in one datasheet, despite…

A 128 KB PDF carrying the code 30WQ03FN, indexed as a schematic but structured like a discrete semiconductor part number.

PDF of 97.3 KB listed as a schematic and named 28C512-513, covering two related parts from the 28C parallel EEPROM family in one document.

A 128 KB PDF named 25C256, which matches the pattern of a serial memory chip part number, so this is most likely a chip datasheet placed in the schematic category.

Covering the 24WC33 and 24WC65, this 56.1 KB PDF is listed as a schematic but is a Catalyst Semiconductor datasheet for 32 Kbit and 64 Kbit I2C serial EEPROMs.

Range datasheet in a 63.4 KB PDF for the Catalyst 24WC01 through 24WC16, a family of small two-wire serial EEPROMs, although the index files it as a schematic.

PDF reference, 112 KB, for the 24C64 serial EEPROM, a 64 Kbit two-wire memory widely used in consumer and automotive electronics.

Datasheet PDF, 83.7 KB, for the 24C01 serial EEPROM, a 1 Kbit (128-byte) memory on the two-wire I2C bus. The name gives no device or board context.
