Compact 90.8 KB PDF identified only by the code 2SK1469. In Japanese semiconductor numbering, 2SK stands for an N-channel FET, so the schematic tag aside, this should be…

Brief 32.2 KB PDF for the 2SK1458LS, identified by its Japanese 2SK code as an N-channel field-effect transistor, with an LS suffix marking a specific variant.

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

A 102 KB PDF covering the 2SK1437 semiconductor, catalogued as a schematic although the file name points to a single part rather than a circuit board.

Component datasheet in PDF, 86.7 KB, for the 2SK546, listed among schematics. Following JIS numbering, 2SK parts are N-channel FETs, so the document covers a single…

Reference PDF, 33.2 KB, for the 2SJ590LS, indexed in the schematic category. Under JIS naming, 2SJ marks a P-channel FET, so the document is expected to hold electrical…

Compact 40.0 KB PDF for the 2SJ348, filed as a schematic but by its part number a datasheet. Under the Japanese JIS designation, 2SJ marks a P-channel FET.

At 414 KB this is one of the larger PDFs in the 2SJ series, covering the 2SJ334. Only the part number appears in the name.

The 2SJ287 is covered in this 96.7 KB PDF. Only the part number is present in the name, so no equipment details can be given.

Indexed as a schematic, the 124 KB PDF named 2SJ193 most probably holds the datasheet for that JIS-numbered P-channel FET.

Named after the 2SJ190, this 93.3 KB PDF sits in the schematic category but, given the JIS 2SJ prefix for P-channel field-effect transistors, should contain the…

Filed as a schematic, this 72.9 KB PDF is titled 2SD1398; in the Japanese JIS scheme the 2SD prefix marks an NPN bipolar transistor intended for low-frequency use, so…

Datasheet PDF for the 2SD1192 transistor, 133 KB, listed in the schematic section of the index. Its name gives nothing beyond the part number.

Only 21.9 KB, this PDF relates to the 2SD1048 and is indexed among schematics, though the name identifies a discrete part.

Compact UTC datasheet, around 14 KB, for the 2SD880 NPN transistor from Unisonic Technologies.

Component datasheet for the 2SD638 NPN transistor, roughly 45 KB in PDF format and catalogued with schematics.

A small 30.6 KB PDF for the 2SC4637LS. The LS suffix appears to denote a particular package or lead variant of the 2SC4637 NPN transistor, so check the outline drawing…

A 172 KB PDF labelled 2SC5174, filed under schematics, though the name points to a component datasheet rather than a board drawing.

An 84.4 KB PDF for the 2SC4547, sorted into schematics but named like a single-component datasheet.

Documentation for the 2SC4450 semiconductor arrives as an 86.3 KB PDF in the schematic listing.

The 2SC4404 is covered by this 114 KB PDF, placed under schematics in the catalogue. According to Japanese JIS numbering, 2SC parts are NPN bipolar transistors, so the…

Small 92.6 KB PDF bearing only the part number 2SC4219. Although the catalogue lists it as a schematic, the 2SC prefix, the JEITA code for an NPN bipolar transistor…

Datasheet for the 2SC4214 transistor, supplied as a 279 KB PDF. The file name holds nothing beyond the part number, so the manufacturer, package and target equipment…

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…

Named 2SC5069 and weighing 107 KB, this PDF is catalogued under schematics but represents a JIS-numbered NPN bipolar transistor, so treat it as a datasheet.

Filed as a schematic, the 112 KB document 2SC5046 is really labelled with a Japanese NPN transistor part number, which suggests a single-component datasheet.

A 103 KB PDF named only after the part 2SC3992, indexed as a schematic but in practice almost certainly a transistor datasheet.

A 117 KB PDF bearing the part number 2SC4860 and nothing else, indexed as a schematic. Since the JIS/JEITA scheme assigns the 2SC prefix to NPN bipolar transistors, the…

Component sheet covering the 2SC3780, a JIS-designated NPN bipolar transistor, in a 126 KB PDF.

Datasheet for the 2SC4921 transistor in a compact 60.9 KB PDF. Under Japanese JIS numbering the 2SC prefix identifies an NPN bipolar transistor, while the name says…
