Small 67.8 KB PDF for the 2SD1854, a part number in the Japanese 2SD series of NPN bipolar transistors, so it is really a datasheet rather than a full schematic.

Datasheet in PDF form, 74.1 KB, for the 2SD1853 transistor from the Japanese 2SD family of NPN bipolar parts, filed here as a schematic.

PDF reference for the 2SD1852, a 2SD-series NPN bipolar transistor, about 96.5 KB and more likely a component datasheet than a circuit diagram.

Component datasheet for the 2SD1851 transistor, supplied as a 93.4 KB PDF and classed as a schematic in the index.

PDF of 126 KB covering the 2SD1842, an NPN bipolar transistor in the JIS 2SD series, so the content is a datasheet rather than a board schematic.

Datasheet PDF, 137 KB, for the 2SD1841, part of the Japanese 2SD range of NPN bipolar transistors, catalogued here under schematics.

Reference sheet in PDF format, 137 KB, for the 2SD1840 transistor from the 2SD family of NPN bipolar devices; despite the schematic label, expect datasheet content.

An 88.0 KB PDF for the 2SD1838, a Japanese-registered NPN bipolar transistor, best treated as a datasheet even though it is indexed as a schematic.

Datasheet for the 2SD1835 NPN bipolar transistor, stored as a 149 KB PDF in the schematic category. The 2SD prefix marks NPN transistors under the Japanese JIS standard.

Compact 37.6 KB PDF for the 2SD1834 transistor, an NPN bipolar part in the 2SD series, most likely a short datasheet rather than a circuit schematic.

PDF document of 112 KB for the 2SD2280, an NPN bipolar transistor in the Japanese 2SD numbering, filed as a schematic but in practice a datasheet.

Datasheet for the 2SD2271 transistor, a 219 KB PDF and one of the larger files in this 2SD group, so it probably includes detailed characteristic curves.

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.

English-language datasheet, as the _E suffix suggests, for the 2SD2260 NPN bipolar transistor, supplied as a 45.3 KB PDF in the schematic section.

A PDF reference sheet for the 2SD2259 transistor, catalogued as a schematic but in practice a component datasheet of 43.3 KB.

Datasheet for the 2SD2258 NPN bipolar transistor, supplied as a 56.8 KB PDF and filed under schematics.

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…

The 2SD2252 is the subject of this 88.6 KB PDF, indexed as a schematic but best treated as a transistor datasheet.

PDF datasheet covering the 2SD2251 NPN transistor, 95.7 KB in size and listed under the schematic category. The name contains nothing beyond the part number.

Reference document for the 2SD2249, a part in the JIS 2SD family of NPN low-frequency bipolar transistors, saved as a 45.3 KB PDF.

Datasheet for the 2SD612K transistor, a 303 KB PDF listed in the schematic section. The K at the end belongs to the type number and indicates a variant of the 2SD612…

A compact 44.3 KB PDF describing the 2SD602 transistor, indexed as a schematic though its content is component data. An _E suffix appears in the name as an edition tag.

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

PDF datasheet of 116 KB for the 2SD600K transistor, placed in the schematic category of the index.

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

Datasheet in PDF format, 229 KB, for the 2SD553 transistor, catalogued among schematics. Nothing besides the part type is stated in the name.

Reference sheet for the 2SD526 NPN bipolar transistor, provided as a 187 KB PDF and filed in the schematic section. Only the part number is given in the name.

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.

PDF data for the 2SD2658LS, 31.1 KB, indexed under schematics. The LS ending is part of the type designation and points to a specific variant or package of the 2SD2658…

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.

Component sheet in PDF for the 2SD2248, 100 KB, which the index places among schematics. No device or board is named, just the transistor type.

Documentation for the 2SD2241 NPN transistor, supplied as a 178 KB PDF and categorised as a schematic. The name provides only the part number.

PDF datasheet, 40.9 KB, for the 2SD2240 transistor, filed under schematics in this index. An _E suffix in the name is an edition marker for the document only.

The 2SD2225 transistor is described in this 44.3 KB PDF, listed as a schematic in the catalogue. The _E tag in the name refers to an edition of the document.
