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 KIA324P, a KEC quad operational amplifier compatible with the widely used LM324, in a DIP package as the P suffix suggests.

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

Reference for the FGH40N60SFD IGBT, with the name stating 40 A and 600 V, supplied as a 463 KB PDF.

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.

Schematic package for Samsung model A047F, which matches the Galaxy A04s numbering, in a 2.01 MB ZIP archive.

Named 3LN02C, this 41.8 KB PDF is filed among schematics but its name is a component-type code with a C suffix and gives no device or board details.

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

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…

PDF document for the 2SK2775, filed under schematics although the part number points to a component datasheet rather than a board drawing.

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

Only the part number 2SJ512 appears in the name of this 455 KB PDF, which the index lists among schematics.

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.

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.

Named only 2SC4161, this 98.6 KB PDF is categorised as a schematic yet, judging by the part number, documents an NPN bipolar transistor under the JIS designation scheme.

Stored under schematics, this 93.8 KB PDF is named for the 2SC4123 and is expected to hold the transistor's datasheet rather than a circuit drawing.
