A 143 KB PDF catalogued as a schematic, covering the 2SD1801 semiconductor part. Under the Japanese JIS numbering system the 2SD prefix marks an NPN bipolar transistor…

Reference sheet for the 2SD2116 NPN transistor, supplied as a 74 KB PDF. Its name follows the Japanese JIS 2SD convention and carries nothing beyond the part number.

Specification sheet in PDF, around 82 KB, for the 2SD1781K NPN transistor of the JIS 2SD series; the K suffix denotes a specific version of the base part.

Datasheet for the 2SD2387 in PDF form, 178 KB, catalogued under schematics. The JIS prefix 2SD denotes an NPN bipolar transistor of the low-frequency family.

For the 2SK3114, a 94.1 KB PDF supplies the component data, filed among the schematics.

PDF reference for the 2SK2993 transistor, 424 KB. The file name carries only the part number, which under the JIS scheme denotes an N-channel field-effect transistor, so…

Very small 26.9 KB PDF for the 2SK2951, likely a short datasheet or summary page given its size.

Datasheet-style PDF, 137 KB, covering the 2SK2550 transistor even though the catalogue lists it as a schematic.

The 2SK2530 is covered by this 42.5 KB PDF document, catalogued under schematics. According to Japanese JIS numbering, 2SK marks an N-channel field-effect transistor…

Part 2SK2399 is the subject of this 423 KB PDF, catalogued as a schematic but in all likelihood a datasheet, since under Japanese JIS numbering 2SK stands for an…

Indexed as a schematic, this 91.9 KB PDF is named only for the part 2SK1899. The 2SK prefix in Japanese numbering marks an N-channel FET, so the file most likely holds…

Covers the 2SK1725 transistor in an 85.8 KB PDF, indexed among schematics but in practice a single-component datasheet.

A 104 KB PDF dedicated to the 2SK1424, an N-channel field-effect transistor going by its JIS 2SK prefix.

PDF datasheet for the 2SK1061 transistor, about 293 KB. Parts prefixed 2SK are N-channel FETs registered under JIS conventions; the name gives no further variant or…

PDF file of about 148 KB describing the 2SJ315, listed in the schematic section. No board or brand is mentioned, only the part number.

The 2SJ312 is documented in this 362 KB PDF, catalogued as a schematic. Beyond the part number the name says nothing about the equipment involved.

Under the schematic category, this 99.0 KB PDF titled 2SJ187 should be the datasheet for a P-channel FET, as the JIS 2SJ prefix indicates.

Listed under schematics, this 110 KB PDF is named for the 2SD1347, an NPN bipolar transistor in the Japanese JIS 2SD series, and is probably its datasheet.

Separate from the UTC version, this 43.2 KB PDF covers the 2SD965 and bears an _E suffix that the name leaves unexplained.

Datasheet-type PDF of 47.9 KB for the 2SD894, placed under schematics. The name holds only the part number, which follows JIS conventions where 2SD indicates an NPN…

Small 27.9 KB PDF for the 2SC4630LS, sorted into schematics though it reads as a transistor datasheet.

Data sheet for the 2SC4502, a small 45.1 KB PDF whose name ends in an E suffix, likely marking an edition or English version, though that is not certain.

Component sheet, 76.2 KB in PDF, for the 2SC4491 transistor. JIS numbering assigns the 2SC prefix to NPN bipolar devices, and despite the schematic category this is a…
