The 232 KB PDF covers the 2SD1947A, a JIS NPN transistor number with an A suffix that the name states.

Datasheet-style PDF of 83.8 KB named for the 2SD1940, an NPN transistor under Japanese JIS numbering, in which 2SD stands for NPN low-frequency types.

A 133 KB PDF for the 2SD1935, a transistor in the Japanese 2SD family, which the JIS standard reserves for NPN low-frequency devices.

Named 2SD1934 with an _E suffix, this 40.2 KB PDF is most likely the datasheet for that NPN transistor, since 2SD is the JIS prefix for NPN low-frequency types.

At only 34.4 KB, this PDF is a short reference for the 2SD1913 transistor. Under Japanese JIS part numbering the 2SD prefix identifies an NPN device for low-frequency…

The 42.4 KB PDF is named for the 2SD2345 and carries an _E suffix, whose meaning the name does not explain.

Catalogued as a schematic, this 156 KB PDF is named after the 2SD1906, a Japanese JIS part number, so it is most likely the component datasheet for that transistor…

A 136 KB PDF for the 2SK2887, with a 1-5 suffix in the name that most likely refers to page range or a document section, though this is not certain.

Second copy of documentation for the 2SK2887, a 139 KB PDF listed under schematics, with the part number written in lower case and no other information in the name.

PDF datasheet, 411 KB, for the 2SK2847, placed in the schematic category of the index. Only the part number is given in the name, with no maker or revision.

PDF for the 2SK2299N, 137 KB, carrying an extra _1-5 suffix in the name whose meaning is not stated; it may mark an alternate edition or page range.

Catalogued as a schematic, this 86 KB PDF is named only after the part number 2SK2273, so it is almost certainly a component datasheet, not a board diagram.

Datasheet-style PDF, 379 KB, for the 2SK1486 N-channel FET, going by the Japanese 2SK type prefix in the file name.

Component documentation for the 2SK1475, a JIS-style part number whose 2SK prefix identifies an N-channel FET.

Compact 30.7 KB PDF covering the 2SJ628, catalogued as a schematic but most likely a single-device datasheet given the part-number name.

Identified solely as 2SJ257, this 96.0 KB PDF most likely documents a P-channel FET, the device class assigned the 2SJ prefix in the JIS system.

Datasheet-style document for the 2SJ227, stored as an 85.3 KB PDF and indexed in the schematic category.

Catalogued as a schematic, this small 46.1 KB PDF is in practice a component document for the 2SC4755, a part number that follows the Japanese JIS scheme, where the 2SC…

Filed as a schematic, this 120 KB PDF is named only after the part number 2SC4402, so it is most likely the manufacturer datasheet for that transistor rather than a…

Datasheet-style PDF of 88.9 KB for the 2SC4361, listed in the schematic category although the file name holds nothing but the part number.

The 2SC5588 is covered by this 332 KB PDF document. Apart from the part number the name gives no detail, so maker and revision are unknown until the file is opened.

Filed as a schematic, this compact 79.7 KB PDF is named for the 2SC4169, a JIS-style designation that belongs to an NPN bipolar transistor, so the content is most…

A 98.4 KB PDF titled with the part number 2SC4162, filed under schematics but in practice expected to be the datasheet for that transistor.

A small 37.1 KB PDF named in lowercase after the 2SC4137, labelled as a schematic but most plausibly a concise datasheet for that part.

A brief 38.9 KB PDF named after the 2SC4119, filed as a schematic but most likely a short datasheet for that transistor.

Datasheet-style PDF for the 2SC5646 transistor, 31.7 KB, placed in the schematic category.

Datasheet-style document for the 2SC5405, stored as a 37.3 KB PDF in the schematic category. Nothing beyond the part number appears in the name.

PDF reference sheet for the 2SC3184, filed in the index as a schematic but named after a single part number in the Japanese JIS scheme.

The 2SC3153 is the subject of this 98.0 KB PDF, catalogued as a schematic though the name points to a discrete-part data sheet.

Part number 2SC2851 with an _E suffix names this 48.7 KB PDF, listed as a schematic. The 2SC prefix follows JIS numbering for NPN bipolar transistors, so a datasheet is…

Compact 57.8 KB PDF named after the 2SC2206, with an _E suffix in the file name whose meaning is not stated.

The 2SC1359 named in this 55.6 KB PDF is, by its 2SC prefix, a Japanese-standard NPN bipolar transistor, so despite the schematic label the document should be a…

Although catalogued as a schematic, this 51.4 KB PDF is named for the 2SC1317, which the JIS 2SC prefix identifies as an NPN bipolar transistor, so a component datasheet…

Component datasheet for the 2SB1434 transistor, filed under schematics but in practice a part reference rather than a board diagram.

PDF document for the 2SA1635, filed under schematics but in fact a component sheet for a discrete transistor; the _1-2 suffix in the name likely marks a part or revision…

A PDF document for the 2SA1604, an 84 KB file listed in the index as a schematic but named after a single discrete part rather than a board.

An 80.4 KB PDF covering the 2sb1260 transistor, listed in the index under schematics. No maker, package or device model is given in the name.
