Stored under a lowercase name, this 52.3 KB PDF covers the 2sd2318 transistor. In the Japanese JIS scheme the 2SD series contains NPN devices for low-frequency duty, so…

Component sheet for the 2SK2886 transistor, delivered as a 424 KB PDF and filed in the schematic category. The name carries only the part number.

Component document for the 2SK2611, a part number in the Japanese JIS scheme where the 2SK prefix marks an N-channel field-effect transistor.

Compact 33.0 KB PDF on the 2SK1834 transistor. The 2SK prefix belongs to the Japanese JIS designation system and means an N-channel field-effect device, so the content…

Datasheet-style PDF for the 2SK669, a part number in the JIS 2SK series used for N-channel field-effect transistors, listed in the index as a schematic.

At just 31.4 KB, the PDF named 2SJ499 is probably a short datasheet or summary sheet, even though it is filed as a schematic.

Catalogued as a schematic, this 93.1 KB PDF is named only after the part number 2SJ281, which follows the Japanese JIS scheme where the 2SJ prefix denotes a P-channel…

PDF document of 41.7 KB for the 2SC4737, filed in the schematic category but named after a part rather than a board.

Named in lowercase for the 2sc4132, this 63.0 KB PDF is classed as a schematic but is better understood as the datasheet for an NPN bipolar transistor, which is what the…

Small 30.5 KB PDF for the 2SC5808 part, an NPN bipolar transistor per the Japanese 2SC designation.

The 2SC5323 is the only clue in this file name, so treat this 122 KB PDF as a probable transistor datasheet even though it sits in the schematic category.

This 145 KB PDF carries only the part number 2SC2884 in its name and is filed as a schematic.

At 190 KB this PDF is larger than most entries here and is named for the 2SC982, an NPN transistor according to the JIS 2SC prefix; the TM suffix in the name is not…

Datasheet for the 2SB1658, filed in the index as a schematic but in practice a component data document in PDF form, 48 KB.

The 2SB1642 PNP transistor is documented in this 181 KB PDF, listed as a schematic though it is a part datasheet.

English-edition datasheet, judging by the _E suffix, for the 2SB1599 PNP bipolar transistor, 43.5 KB in PDF.

Component data for the 2SB1527 in PDF form, roughly 73 KB, catalogued as a schematic though the bare part number suggests a datasheet.

PDF datasheet-style file for the 2SB1290 transistor, only 38.7 KB, so likely a brief sheet of a few pages. The name carries no other details such as package or maker.

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.

Small PDF reference, 47.7 KB, for the part 2PD601A, with the trailing 4 most likely the sheet revision.

Short 49.9 KB PDF document for the 2N6284, a JEDEC-registered discrete semiconductor, catalogued as a schematic though it is most likely the part's datasheet.

A small 209 KB PDF filed under schematics, named only with the number 28101 and no brand, model or board revision.

PDF document of 202 KB named 25CTQ, a series-style code with no voltage suffix, so it probably covers a family of related components in datasheet form.

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.

Filed under schematics, this PDF of 309 KB is named only after the 24C64 part number, so it is most likely the datasheet for a 64 Kbit (8 KB) serial EEPROM on the I2C…

PDF datasheet covering the 24AA32A and 24LC32A, serial EEPROMs holding 32 Kbit and addressed over the I2C two-wire bus.

PDF datasheet of 338 KB covering the 24AA01 and 24LC01B, the 1 Kbit members of this I2C serial EEPROM line.

Sony VAIO schematic in PDF format, 847 KB, covering the MBX-217 motherboard, with M851 most likely the ODM project code carried alongside it.

Archive for Wistron board number 08530-2, a 47.9 KB RAR where the -2 suffix marks a particular variant or revision within the 08530 project.

Zip archive of schematic material for the Huawei Mate 20X phone, per the name. Phone service schematics like this usually show the PMIC rails, battery and charging path…
