PDF for the 74AC00, a quad 2-input NAND gate in the advanced CMOS family, 302 KB, catalogued as a schematic; the name drops the digit before input, but the part number…

PDF for the KA4558, a dual operational amplifier in the KA series, equivalent in function to the familiar 4558 dual op amp, size 121 KB.

Part document for the 2SC4517, a 27.9 KB PDF listed as a schematic; the name holds only the part number.

Datasheet-style PDF for the BU2508DX, roughly 80 KB, indexed under schematics. This is a well known horizontal deflection transistor for CRT TVs and monitors, and the D…

Datasheet-style PDF covering the BD233, BD235 and BD237 family of medium-power transistors, filed here under schematics.

PDF data for the BC328 PNP transistor, the name listing minus 30 V and minus 800 mA ratings, filed under schematics at 53.5 KB.

The 3N258 is the subject of this 42.2 KB PDF, indexed as a schematic but in practice a component reference.

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.

Another copy of documentation for the 2SD1458 NPN transistor, stored as a 48.8 KB PDF under a lowercase file name.

The name 2sd1455 refers to a JIS-registered NPN transistor, and this 53.0 KB PDF is most likely its manufacturer datasheet, although the index lists it as a schematic.

A fairly detailed 200 KB PDF for the 2SD2352, a JIS-numbered NPN transistor, where the 2SD prefix denotes NPN low-frequency parts.

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…

A compact 23.3 KB PDF for the 2SK2772, an N-channel FET according to the JIS 2SK naming convention, catalogued here as a schematic.

A 135 KB PDF covering the 2SK2711 transistor. The extra 1-5 token in the name is not explained and may point to a page range or document revision.

Datasheet-style PDF for the 2SK1412LS, a Japanese 2SK-series N-channel field-effect transistor, filed in the index under schematics.

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.

The 2SJ419 is covered by this 100 KB PDF, filed under schematics though the part number points to a discrete transistor datasheet.

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

Datasheet in PDF form for the 2SC4696, filed in the index under schematics although the name points to a discrete part document rather than a board diagram.

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.

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.

The 2SC2982 is the only information this 147 KB PDF name provides; it is filed as a schematic.

Filed under schematics, this 49.7 KB PDF covers the 2SC1318A, an NPN transistor in JIS numbering; the A suffix denotes a variant of the base 2SC1318 type, often with…
