Small PDF of 92.1 KB filed under schematics, though its name is simply the part number 2SD1998, so it is almost certainly a component datasheet rather than a board…

Small 45.6 KB PDF named 2SD1902, a Japanese standard transistor number; despite the schematic label it is most probably a short datasheet.

A compact 134 KB PDF titled with the part number 2SK2839 and catalogued as a schematic.

Smaller 137 KB PDF tied to the 2SK2606, a JIS-style designation where 2SK indicates an N-channel field-effect transistor.

Short datasheet-type PDF of 30.0 KB for the 2sk2588, an N-channel FET according to the JIS 2SK prefix.

Small 30.0 KB PDF covering the 2SK2047 transistor. Under the JIS naming system the 2SK prefix marks an N-channel FET, so this is best treated as a part datasheet rather…

Compact 42 KB PDF for the 2SJ340, catalogued among schematics although the name is a transistor part number. Nothing else about a device or board is stated.

The 2SJ339 appears in this small PDF of roughly 40.7 KB. The name carries only the part number, with no hint of the equipment it came from.

Small 46.2 KB PDF for the 2SC5501. Under the Japanese JIS scheme, a 2SC prefix marks an NPN transistor intended for high-frequency use.

At only 24.2 KB, the 2SC3989 PDF is a compact document, probably a short datasheet or summary page for this JIS-numbered NPN bipolar transistor despite being indexed as…

Small 41.6 KB PDF for the 2SC5388, a JIS-numbered NPN bipolar transistor; the file name states only the part number, so package, maker and application are not given.

Component document for the 2SC4809 transistor, filed under schematics but by its name and small size most likely a manufacturer datasheet.

Small 39.7 KB PDF for the 2SC3526, carrying an _E suffix in its name whose meaning, perhaps a language edition or document revision, cannot be confirmed from the name…

Named for the 2SC2995, this 510 KB PDF is listed as a schematic but most likely holds the datasheet for a JIS-numbered NPN transistor, as the 2SC prefix indicates.

Component datasheet for the 2SB1644, a small 48 KB PDF catalogued under schematics. JIS numbering places any 2SB part among PNP bipolar transistors for low-frequency…

Small 39.6 KB PDF containing the datasheet for the 2sb1616, catalogued as a schematic entry.

Small PDF document for the 2SB1537, a Japanese JIS-registered transistor part number, catalogued here as a schematic although a part code like this normally points to a…

A 41.5 KB PDF for the 2SB970 transistor, with an _E suffix the file name leaves unexplained.

PDF document for the 2SA1246 semiconductor, filed under schematics but named only by the part number, so it is most likely the component datasheet.

Small 37.6 KB PDF for the 2SA1900, written in lowercase in the original name and placed in the schematic category; the content is most likely a brief datasheet.

Small 41.8 KB PDF for the 2SA1890, with an _E suffix in the name that commonly marks an English-language edition of a Japanese datasheet, though the file does not…

A 28.6 KB PDF named after the 2SA1179, a PNP transistor under the JIS 2SA designation. With only a part number in the name, it is almost certainly a brief datasheet…

A 46.1 KB PDF datasheet covering the 2N3019 transistor, indexed in the schematic category.

PDF datasheet of 73.0 KB for the 2N2906 transistor, stored in the schematic section of the index.

PDF sheet for the 1SV160, catalogued as a schematic. The name adds V1, probably a document version, and sot323, the small three-lead SOT-323 surface-mount package.

PDF for the 1SV316, catalogued under schematics, with UV and sot323 added to the name. SOT-323 is a small three-lead surface-mount package, while the UV token is not…

A small PDF of 69.9 KB, listed under schematics and titled with the part number 1SV268.

Component document for the 1SS133, catalogued as a schematic but most likely a datasheet for a small-signal diode, since the 1SS prefix is the Japanese JIS-style…

Component reference for the 1SS401, stored as a 77.2 KB PDF under the schematic type. The name holds just the part number, so this is most likely a manufacturer…

Part documentation for the 1SS400, an 86.6 KB PDF classed as a schematic. The 1SS designation belongs to the Japanese family of small-signal silicon diodes, so expect a…

A 67.7 KB PDF reference for the 1SS395, recorded as a schematic in the index. The 1SS prefix is the Japanese JIS-style designation for small-signal diodes, so the…

A 98.0 KB PDF for the 1SS390, the largest of this group and filed as a schematic type. The name holds only the part number.

Catalogued as a schematic, this 69.5 KB PDF is named after the part number 1SS381, so it is most likely a component data sheet.

The name identifies only the part 1SS377, so this 69.8 KB PDF is best treated as a diode data sheet even though it is indexed as a schematic.

The file name gives the part number 1SS365 and nothing more, and at 49.2 KB the PDF is the size of a typical short component data sheet.

The name 1SS360F gives a small-signal silicon diode number, per the JIS 1SS prefix, followed by an F suffix whose meaning the name does not state.

A compact PDF of 53.8 KB indexed as a schematic, named only after the part number 1SS350.

Only the part number 1SS336 appears in this 68.3 KB file name, and the PDF is filed under schematics.

The 69.8 KB PDF here is labelled with nothing more than 1SS321, a part number in the Japanese small-signal diode designation used largely by Toshiba.

Larger than most of its neighbours at 123 KB, this PDF is named only 1SS313 and gives no device or board details.
