HCF4050 reference document in PDF format, 175 KB, covering the 4050 hex non-inverting buffer in its HCF-prefixed version.

Component documentation for the 2SD2257 transistor, in PDF form at 180 KB. Although the index lists it as a schematic, the file name points to a single discrete part…

Covers the 2SD2218 NPN transistor in a 122 KB PDF filed under the schematic category. Only the transistor type appears in the name.

Covering the 2SD2645, this 29.3 KB PDF sits in the schematic index although the name suggests a component datasheet.

Datasheet-type PDF, 30.8 KB, for the 2SD2627LS, catalogued as a schematic. The LS suffix is part of the type designation and likely refers to a specific variant or…

A 41.4 KB PDF covering the 5HP02C part, indexed under schematics. Only the component code is present in the name, with C most likely denoting the package type.

Part datasheet for the 2SD1782K, an NPN transistor named under the Japanese JIS scheme, with the K suffix indicating a particular variant or package.

The 2SD2079 PDF, 219 KB in size, is indexed as a schematic yet corresponds to a single discrete component.

Transistor documentation for the 2SD1667, 136 KB in PDF format. Nothing beyond the part number appears in the name.

At 198 KB, the PDF for the 2SD1658 is one of the larger sheets in this group, though it still names only the part.

The 2SD1628 is covered in this 88.3 KB PDF, catalogued with schematics though it relates to a single transistor.

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

Document for the 3SK227 semiconductor, stored as a 30.6 KB PDF and catalogued under schematics.

Compact 43.6 KB PDF named for the 3N249 and filed as a schematic, although it is almost certainly a component datasheet.

The 3N248 is covered by this 43.6 KB PDF, indexed under schematics but named only by its JEDEC part number.

Part number 2SD2459 names this 41.2 KB PDF, followed by an unexplained E tag; it is catalogued as a schematic.

The 2SD1511 NPN transistor is the subject of this 56.9 KB PDF, filed under schematics in the index. JIS numbering assigns 2SD to low-frequency NPN bipolar parts.

The name carries only a part number, 2SD1905, which points to a semiconductor datasheet even though the entry is filed under schematics.

Filed under schematics, though the file name is simply the JIS part number 2SD1903, so expect a component datasheet in this 131 KB PDF.

Tiny 30.2 KB PDF named 2sk65, a JIS part number that indicates a component datasheet, although it is filed as a schematic.

Covering the 2SK3335, this small PDF (32.6 KB) is a part datasheet placed in the schematic category.

The 2SK3291 transistor is the subject of this 34.2 KB PDF, filed as a schematic although it works as a datasheet.
