The 2SK1867 is named in this small 33.9 KB PDF, catalogued under schematics. Because 2SK is the Japanese prefix for N-channel field-effect transistors, expect a brief…

Datasheet PDF for the 2SK1771, about 305 KB in size. Under JIS conventions, the 2SK prefix identifies an N-channel FET; the file is listed as a schematic but the name…

Part datasheet in PDF form for the 2SK1727, about 86 KB. Its 2SK prefix marks an N-channel FET under the Japanese transistor naming system; manufacturer, package and…

Labelled 2SK1451, this 111 KB PDF sits in the schematic section but by name looks like a transistor data sheet. The JIS 2SK code belongs to N-channel FETs.

Named for the 2SK1445, this 108 KB PDF falls under the schematic category but most likely contains the full transistor data sheet.

PDF for the 2SK1053 transistor, 107 KB, filed as a schematic but by its name a single-part datasheet.

At 130 KB, this PDF documents the 2SD1060, the largest of its neighbouring files and filed as a schematic. Nothing beyond the part number appears in the name.

A 271 KB PDF for the 2SC5232, listed as a schematic yet named like a single-component datasheet. JIS numbering gives the 2SC prefix to NPN bipolar transistors.

A 136 KB PDF for the 2SC4616, listed among schematics though the name only carries a component part number, implying a transistor datasheet.

Part-number named PDF, 205 KB, for the 2SC5142 transistor; though catalogued as a schematic, it is likely the manufacturer datasheet.

A 195 KB PDF labelled with the transistor type 2SC4210. No device, board or manufacturer is named; the 2SC prefix simply tells us, through the Japanese JEITA system…

Component documentation for the 2SC5465 in a 146 KB PDF, catalogued as a schematic. The part belongs to the JIS 2SC range of NPN transistors, so the content is most…

Listed among schematics, this 155 KB PDF is named after the transistor type 2SC3788 and gives no further details such as maker or case.

PDF component sheet, 60.3 KB, covering the 2SC4920 NPN transistor from the JIS 2SC series.

Around 173 KB of PDF datasheet material for the 2SC5307, an NPN bipolar transistor in the Japanese JIS 2SC series. The name gives no maker, package or intended circuit.

A 108 KB PDF covering the 2SC4890, categorised under schematics but in substance a single-component datasheet.

The 2SA1525 transistor gives its name to this 30.8 KB PDF, which is filed as a schematic but presumably contains the datasheet.

An 87.9 KB PDF for the 2SA1509 transistor, listed under schematics but named as a single component. JIS numbering identifies 2SA parts as PNP transistors.

Reference PDF of 176 KB for the 2SA1425 transistor, carrying no information in its name beyond the part number.

Documentation for the 2SB827 transistor in a 103 KB PDF, indexed among schematics. JIS part codes beginning with 2SB are assigned to PNP devices classed for…

For the 2SA1356, this 177 KB PDF carries just the part number, so it is most probably the device datasheet rather than a full circuit diagram.

PDF for the 2SA1310, 41.2 KB, carrying an E suffix in the name whose meaning is not stated and may simply mark a document edition.

PDF, 250 KB, for the 2SA1255 PNP transistor, with 2SA being the Japanese JIS designation for that class.

Lowercase-named PDF for the 2SA1834 transistor, 40.6 KB, filed among schematics. In the JIS scheme, the 2SA designation marks a PNP bipolar transistor.

The name gives just 2N5638, so this 26.3 KB PDF has no board, device or revision information.

PDF datasheet, 44.7 KB, describing the 1T368 transistor, catalogued in the schematic section.

Data for the 1T367 transistor in a 44.2 KB PDF, stored with schematics. The 1T prefix belongs to the old Soviet semiconductor designation, indicating a germanium…

The 1SS383 is covered in this 69.1 KB PDF, catalogued as a schematic though most likely a datasheet, as 1SS is the Japanese designation for small-signal silicon diodes.

This 80.9 KB PDF for the 160cnq035 is filed as a schematic, but the code matches a high-current dual Schottky rectifier, the 035 ending usually indicating 35 V.

The name 160cmq is a component code rather than a board number, so this 56.5 KB PDF, although categorised as a schematic, is most plausibly a datasheet for a…

Indexed under schematics, this 83.7 KB PDF named 155cmq015 has the form of a Schottky rectifier part number, with 015 typically meaning a low 15 V reverse rating suited…

At 616 KB, 1B31.pdf is the largest of the 1B-coded files and is listed as a schematic, yet its name says nothing about device, maker or board revision.
