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

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.

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.

A small 40.3 KB PDF for the 2SK2867, filed as a schematic; the modest size suggests a short datasheet or summary page. The name contains nothing but the part number.

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.

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.

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…

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.

Very small at 26.8 KB, this PDF is identified only as 2SC4826, a JIS transistor code in which 2SC marks an NPN type.

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.

Small 40.7 KB PDF named 2SC2925 with an added _E suffix, classified here as a schematic.

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…

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.

Reference sheet for the 2SA1244 transistor in PDF form, 295 KB, listed as a schematic even though the name gives nothing beyond the part number and the file is most…

Part document for the 2SA1735 transistor, stored as a 151 KB PDF and catalogued under schematics.

PDF of 97.5 KB covering the 2SA1729, a component listed in this index as a schematic although the name describes a single part.

Part reference for the 2SA1708, saved as a 154 KB PDF. No device, brand or board number is present in the name, only the component designation.

PDF of 34.7 KB for the 2SA821S, one of the smallest documents in this group, with only the part number in its name.

Brief PDF document of 25.6 KB named 2pg351, listed as a schematic. Apart from the part-like code, the name carries no model, brand or revision, so treat it as a short…

Component data in a 47.8 KB PDF named for 2PD1820A, with the suffix 2 likely marking a document revision.
