PDF document for the 2SD2028, 91.1 KB, filed in the schematic category. Only the part number is given.

PDF of 363 KB for the 2SK192A, listed among schematics but named after a single JIS part, with an A suffix that the name explicitly includes.

Datasheet PDF of 45.2 KB for the 2SK3280, categorised here as a schematic. The 2SK prefix indicates an N-channel field-effect transistor according to JEITA naming.

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…

For the 2SK2985 transistor, this 424 KB PDF is filed as a schematic but its name indicates a single-component datasheet.

Lowercase-named PDF of 136 KB covering the 2SK2503, catalogued as a schematic though it relates to a single transistor.

Compact 36.9 KB PDF named for the 2SK2375, indexed under schematics but most likely a datasheet for an N-channel field-effect transistor, as indicated by the JIS 2SK…

A 134 KB PDF identified solely as 2SK2219, placed in the schematic category but most likely a transistor datasheet.

PDF of 101 KB for the 2SK1849 transistor, listed with schematics. In JIS numbering the 2SK prefix identifies an N-channel FET, so this should be the device datasheet…

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

Indexed under schematics, this 110 KB PDF carries the part number 2SK1447 and is likely its full component data sheet.

Here the 2SK1422 transistor is documented in a 103 KB PDF filed under schematics, though content is most likely a datasheet rather than a board diagram.

A small 98.7 KB PDF about the 2SK1416, catalogued under schematics but most likely a component datasheet.

Small 29.4 KB PDF bearing only the part number 2sj146. The 2SJ prefix in Japanese JIS naming designates a P-channel field-effect transistor, so treat this as a compact…

PDF of roughly 332 KB dedicated to the 2SJ610 part number and catalogued as a schematic.

A 320 KB PDF for the 2SJ380, catalogued under schematics but by its number a transistor datasheet. In JIS designation, 2SJ parts are P-channel field-effect transistors.

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.

PDF of 245 KB titled 2SJ200, which by Japanese JIS convention is a P-channel field-effect transistor; the contents are probably the datasheet rather than a circuit…

Covering the 2SD1213 transistor, this PDF of 116 KB is indexed under the schematic type.

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

Documentation for the 2SC4623 transistor in PDF form, roughly 128 KB, indexed as a schematic although the part-number name indicates a datasheet.

Compact 74.2 KB PDF titled 2sc5161 in lowercase, listed among schematics but almost certainly a single-part datasheet.

Reference PDF of 220 KB for the 2SC4544, indexed as a schematic though the name is a JIS transistor part number, pointing to a datasheet.

The 2SC4527 data sheet, a 310 KB PDF filed under schematics but in practice a component specification.

Part documentation for the 2SC4519, an 85.9 KB PDF that is categorised as a schematic but is a component datasheet.

The 2SC4504 transistor is covered by this 83.2 KB PDF data sheet. Its 2SC prefix follows Japanese JIS numbering for NPN bipolar devices; the name gives no manufacturer…

Component documentation for 2SC4460 in a 108 KB PDF file. The number follows Japanese JIS registration, where the 2SC prefix denotes an NPN transistor for high-frequency…

Part code 2SC4440 is all the 97.3 KB PDF name reveals, and the catalogue places it under schematics.

Short 40.3 KB PDF describing the 2SC5578 transistor. No manufacturer, package or version appears in the file name.

PDF reference for the 2SC4248 transistor, 300 KB in size. Beyond the part number the file name gives no information about manufacturer, package or revision.
