PDF document for the 2SK3569 component, catalogued as a schematic although the misspelled name indicates it is really a datasheet for this N-channel FET from the 2SK…

Short 34.2 KB PDF for the 2SD2261, an NPN bipolar transistor from the 2SD family, catalogued as a schematic though the content should be a brief datasheet.

Covers the 2SD601A, an NPN bipolar transistor from the JIS 2SD series, in a 43.1 KB PDF file.

The 2SD592 NPN transistor is documented in this 50.3 KB PDF, which the catalogue lists as a schematic.

A small 33.3 KB PDF covering the 2SD330 transistor, listed as a schematic though it documents a single discrete part. The name carries no other details.

Datasheet for the 2SD2650 transistor, a 29.7 KB PDF filed in the schematic category. The file name states the part number and nothing else.

Datasheet for the 2SD2223, in PDF form at 133 KB and indexed as a schematic. The name identifies only this transistor type.

Datasheet for the 2SD2216J, a 40.5 KB PDF listed as a schematic. The J is part of the type designation and marks a variant of the 2SD2216, so the exact suffix should be…

A 43.6 KB PDF tied to the 2SD1820, including an E suffix that the name does not explain.

A 44.1 KB PDF for the base 2SD2177 transistor, the name also carrying an _E suffix. The 2SD prefix in the Japanese JIS scheme marks an NPN bipolar device for…

Here the subject is the 2SD2167, delivered as a 51.2 KB PDF filed as a schematic. By JIS convention the 2SD prefix belongs to NPN bipolar transistors for low-frequency…

Compact 27 KB PDF named 5HP01M, catalogued as a schematic but pointing to a single semiconductor component.

A 171 KB PDF for the 4N39 and 4N40 optocouplers, listed under schematics but in practice a component datasheet.

The 2SD1724 part number is all the name gives, and the 145 KB PDF is tagged as a schematic, though a file named this way is normally a transistor datasheet.

Labelled 2SD2526, this 192 KB PDF contains reference data for a Japanese-coded transistor rather than a device-level circuit.

For the 2SD2499 transistor, this 269 KB PDF provides component-level data despite its schematic category.

This datasheet PDF of 179 KB covers the 2SD2480 transistor and contains no further detail in its name.

Named for the 2SD2462, this 184 KB PDF is effectively a datasheet for a Japanese-registered transistor.

A 100 KB PDF for the 2SD1685, categorised as a schematic but named in the manner of a single-part datasheet.

Covering the 2SD1668, this 104 KB PDF is listed as a schematic, though the name is a discrete transistor code.

Named for the 2SD1618 transistor, a 116 KB PDF listed as a schematic but most plausibly the part's datasheet.

PDF of 184 KB bearing the part number 2SD1410A, kept in the schematic category but best treated as the transistor's datasheet, with the A suffix denoting a variant of…

Carrying only the part number 2SD1885, this 93.4 KB PDF is filed as a schematic, though it reads as a transistor datasheet by name.

Reference PDF for the 2SD1882, a JIS-registered Japanese semiconductor, filed in the index under schematics although it is most likely a component datasheet.

A 90.1 KB PDF named after the 2SD1877 semiconductor and filed as a schematic, although its content is expected to be a component datasheet.
