PDF of 126 KB covering the 2SD1842, an NPN bipolar transistor in the JIS 2SD series, so the content is a datasheet rather than a board schematic.

PDF datasheet of 116 KB for the 2SD600K transistor, placed in the schematic category of the index.

Component reference for the 2SD2568, a 44.6 KB PDF in the schematic category. The 2SD prefix follows JIS numbering for NPN bipolar transistors used in low-frequency…

A 277 KB PDF covering the 2SD2539, a part number in the JIS 2SD family, which denotes NPN bipolar transistors for low-frequency circuits.

Datasheet for the 2SD1784 transistor in PDF format, roughly 153 KB, listed among schematics. The 2SD designation marks an NPN low-frequency device under the JIS system.

Transistor reference for the 2SD2048, 78.9 KB, in PDF format and listed among schematics.

Datasheet-type PDF for the 3SK271, around 32.7 KB, catalogued in the schematic category.

Datasheet PDF for the 2SD1512, 40.8 KB, catalogued in the schematic section. The JIS prefix 2SD denotes an NPN bipolar transistor of the low-frequency type, and the E…

The 2SK3092 is described in this compact 31.3 KB PDF, catalogued as a schematic but acting as a datasheet. Under JEITA designations, a 2SK part is an N-channel FET.

Covering the 2SK2952, this PDF of 414 KB is a discrete transistor document rather than a full circuit, as the JIS 2SK prefix indicates an N-channel field-effect…

Document for the 2SK2493 field-effect transistor in PDF form, 384 KB, listed under schematics in the catalogue.

Reference sheet for the 2SK2382, a 412 KB PDF placed under schematics, though the JIS-format number marks it as a datasheet for an N-channel FET.

The 2SK2094 N-channel FET is the subject of this 127 KB PDF, which is catalogued as a schematic though the bare part-number name points to a datasheet.

Reference sheet in PDF form (98.9 KB) for the 2SK1909 transistor, catalogued under schematics.

Small 36.4 KB PDF for the 2SK1614, an N-channel field-effect transistor according to the Japanese 2SK designation.

PDF datasheet, 117 KB, for the 2SK1460, a Japanese-designated N-channel field-effect transistor, filed under schematics in the catalogue.

A 294 KB PDF for the 2SK209, filed as a schematic. In JIS semiconductor nomenclature the 2SK series is N-channel FETs, so this is effectively a component datasheet.

The 2SJ305 is described in this 335 KB PDF, listed among schematics. No board number or brand appears in the name.

Datasheet-style PDF, 99.8 KB, for the 2SC5296 transistor. Under Japanese JIS naming, 2SC parts are NPN bipolar types, so expect specifications rather than a full circuit…

A 35.0 KB PDF relating to the 2SC5270. The 2SC prefix denotes an NPN bipolar transistor in the Japanese JIS system, so the document is most probably a compact datasheet…

The 2SC4685 is documented in this 186 KB PDF, filed as a schematic though the name is a transistor part number.

Transistor documentation for the 2SC4678 in a 220 KB PDF file, sorted into the schematic category.

Here is the 106 KB datasheet-style PDF for 2SC4637, a JIS-numbered NPN bipolar transistor.

Datasheet-type PDF, about 236 KB, for the 2SC5176 transistor, catalogued as a schematic though the name contains only the part number.

A 154 KB data sheet in PDF form describing the 2SC4488. Under JIS naming, the 2SC prefix denotes an NPN bipolar transistor, and the file covers that single component…

Covering the 2SC4483, this 126 KB PDF is a semiconductor data sheet; the 2SC prefix follows JIS rules for NPN bipolar transistors.

Datasheet candidate for the 2SC4455 transistor, a 100 KB PDF although filed with schematics.

Here is a 297 KB PDF named 2SC5590, sorted under schematics but bearing only a component number, so it should be the datasheet for that part.

A 249 KB PDF for the 2SC4203, filed as a schematic but named with only a semiconductor type number.

Named after the 2SC5707, this 37.8 KB PDF should be a datasheet for an NPN bipolar transistor, as the 2SC prefix indicates under JIS numbering.

Datasheet PDF, 41.0 KB, covering the 2SC3954, a JIS-numbered NPN bipolar transistor, and listed in the schematic category.
