Component document in PDF for the 2SK2555, filed under schematics although the part number points to a discrete semiconductor rather than a board.

Reference PDF of 218 KB for the 2SC4754, indexed as a schematic but named after a single semiconductor part.

Catalogued as a schematic, this 240 KB PDF carries only the part number 2SC4200 in its name, which points to a component datasheet rather than a board diagram.

Listed as a schematic, this 28.7 KB PDF is named only after the part number 2SC5681, which in the Japanese JIS scheme marks an NPN bipolar transistor, so it is most…

Component sheet in PDF format for the 2SA1541 transistor, 39.2 KB in size. Only the part number appears in the name, so no board, device or manufacturer can be inferred.

Small 29.3 KB PDF covering the 2SA1436 transistor. In the Japanese JIS designation system a 2SA number denotes a PNP transistor, nominally a high-frequency type, though…

Brief 41.1 KB PDF for the 2SA921, with an _E suffix in the name that likely marks an English-language edition, though that is not certain.

This PDF of 71.0 KB is indexed as a schematic for the 2N6520, a JEDEC 2N-series discrete semiconductor number.

Labelled 2SC5256, this 165 KB PDF most likely contains the datasheet for that JIS-coded NPN transistor; an FT-suffixed variant document also exists.

For the 2SC5703 there is this 167 KB PDF, catalogued as a schematic but almost certainly a part datasheet, since 2SC denotes an NPN bipolar transistor in the JIS system.

Sheet for the 2SB156, labelled in the name as a PNP transistor rated -20 V and -500 mA, provided as a 39.7 KB PDF and indexed under schematics.

Small PDF of about 30 KB filed as a schematic for the 3SK241 part number. The 3SK prefix is the Japanese JIS designation for four-lead field-effect transistors…

At 45.2 KB this is a short PDF named for the 2SC4160 part number; it is filed as a schematic but most likely amounts to a brief transistor datasheet.

PDF document for the 2SB1185 transistor, filed under schematics and 133 KB in size. The trailing 1-5 in the name is not explained; it may refer to pages or a document…

Reference document for the 2SA1730 transistor in PDF form, 97.6 KB in size. Only the part number appears in the name, so no specific equipment can be tied to it.

Short 28.1 KB PDF for the 2SD2627, catalogued as a schematic though it is most likely a brief datasheet.

Reference PDF for the 2SA1478 transistor, 155 KB, catalogued in the schematic section. The JIS-style 2SA prefix indicates a PNP bipolar transistor.

The name 1N957-991B indicates a range of JEDEC 1N part numbers with a B suffix, so this 77.1 KB PDF likely covers a whole family of diodes in one datasheet rather than a…

Component documentation for the 2SK2713, catalogued here as a schematic but in practice a small 144 KB PDF typical of a part datasheet.

Filed under schematics, this small 43.8 KB PDF actually covers the 2SC5304LS, a part number following the Japanese JIS scheme where the 2SC prefix marks an NPN…

PDF datasheet, 32.8 KB, for the 2SK963 N-channel FET. The 2SK prefix follows the JIS numbering convention for N-channel field-effect transistors; the name gives no…

Only 29.4 KB, this PDF references the 2SC5696, an NPN bipolar transistor according to JIS numbering where 2SC marks such parts. The name offers no further specifics.

This 74 KB PDF covers the 2SC2411K, an NPN part in the JIS 2SC series with a K suffix. Although listed as a schematic, it is most likely the manufacturer datasheet.

A small 41.5 KB PDF for the 2SD1458, a part number in the Japanese JIS scheme where 2SD identifies an NPN low-frequency transistor.

Part-number document for the 2SJ561, stored as a 160 KB PDF and tagged as a schematic. In Japanese transistor numbering, 2SJ stands for a P-channel FET, so the content…

Titled 2SK2378, this 26.7 KB PDF is the smallest in its series and is listed under schematics, but the JIS part number indicates a datasheet for an N-channel FET.

Reference datasheet for the 2SK1052, delivered as a 104 KB PDF with no other details in the name.

The 2SA1405 transistor is described in this 124 KB PDF, listed under the schematic type. Its JIS designation places it among PNP parts for high-frequency use.
