PDF sheet of about 42 KB for the 3N259, catalogued under schematics though the file name is simply a JEDEC part number.

Component sheet covering the 3N254, delivered as a 42.2 KB PDF and indexed as a schematic. JEDEC numbers beginning with 3N denote registered devices having four leads.

A compact 30.1 KB PDF for the 2SK2682LS. The base 2SK2682 follows JIS numbering for N-channel field-effect transistors, while the LS suffix marks a variant, often a…

Datasheet-style PDF of 27.2 KB for the 2SK2682, a JIS-designated N-channel FET; it is listed under schematics but describes a single component.

Datasheet PDF, 413 KB, referencing the 2SK2601, catalogued as a schematic. Per JIS semiconductor naming, the 2SK prefix denotes an N-channel FET; no other details such…

Datasheet PDF of 36.1 KB for the 2sk2572, filed under schematics although nothing in the name points to a board or appliance.

Reference sheet in PDF form for the 2SK2349, sized 54.7 KB and listed in the schematic category.

At 316 KB this 2SK2145 document is larger than most in the set, so it may hold extra characteristic curves or several package variants.

The 2SK1747 is the subject of this 184 KB PDF. Japanese JIS designation 2SK means an N-channel field-effect transistor, so the file is probably the manufacturer…

Labelled 2SK1451, this 111 KB PDF sits in the schematic section but by name looks like a transistor data sheet. The JIS 2SK code belongs to N-channel FETs.

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.

A 31.0 KB PDF for the 2SJ597, stored in the schematic category although it is named like a single-part datasheet.

Documentation for the 2SJ378 P-channel FET in a 418 KB PDF, listed as a schematic though really a datasheet.

PDF reference for the 2SJ338, 113 KB, filed under the schematic category. No board number, brand or revision is present in the name.

Component datasheet in PDF form for the 2SJ284, roughly 81.4 KB. The file name names only this part, with no device, board or revision mentioned.

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

An 88.9 KB PDF for the 2SD1247, indexed as a schematic although the name identifies a single semiconductor.

PDF of 30.5 KB for the 2SD1047P, a variant carrying a P suffix that the name does not explain; it may denote a package or grade, so compare it with the plain 2SD1047…

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.

Close in number to its neighbours, 2SC4645 is another JIS-coded NPN transistor, and this 147 KB PDF is probably its datasheet.

A 136 KB PDF for the 2SC4616, listed among schematics though the name only carries a component part number, implying a transistor datasheet.

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

2SC5154 is the only detail in this 198 KB PDF name, and that JIS designation points to an NPN bipolar transistor of the high-frequency group, so treat the file as a…

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

Datasheet PDF of 42.3 KB for the 2SC5638, listed in the schematics section though the name refers to one transistor.

Transistor datasheet in PDF for the 2SC4247, 302 KB, indexed with schematics rather than board diagrams. Only the part number is provided in the name.

Datasheet PDF, 52.4 KB, for the 2SC5574, with the type number written in lowercase in the original name.

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…

The 2SC4108 is the only detail this 94 KB PDF name provides, and the index files it as a schematic.

PDF of 49.6 KB named 2SC5565, catalogued with the schematics although it refers to a single semiconductor.

Datasheet-type PDF for the 2SC5564, 50.0 KB, placed in the schematic category. No model or board appears in the name; the 2SC prefix indicates an NPN transistor for…

PDF datasheet, 41.0 KB, for the 2SC5506 NPN bipolar transistor, held in the schematic section.

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.

Reference sheet for the 2SC3990 transistor, stored as a 104 KB PDF and catalogued under schematics.

A 52.2 KB PDF with the lowercase name 2sc4938, indexed under schematics. The part number is the sole detail.

Listed among schematics, this 155 KB PDF is named after the transistor type 2SC3788 and gives no further details such as maker or case.
