Datasheet for the 2SD2223, in PDF form at 133 KB and indexed as a schematic. The name identifies only this transistor type.

A 43.6 KB PDF tied to the 2SD1820, including an E suffix that the name does not explain.

Here the subject is the 2SD2167, delivered as a 51.2 KB PDF filed as a schematic. By JIS convention the 2SD prefix belongs to NPN bipolar transistors for low-frequency…

Family datasheet spanning the 4N29 through 4N33 optocouplers, a 157 KB PDF listed in the schematic category.

The 2SD1724 part number is all the name gives, and the 145 KB PDF is tagged as a schematic, though a file named this way is normally a transistor datasheet.

Labelled 2SD2526, this 192 KB PDF contains reference data for a Japanese-coded transistor rather than a device-level circuit.

For the 2SD2499 transistor, this 269 KB PDF provides component-level data despite its schematic category.

Covering the 2SD1668, this 104 KB PDF is listed as a schematic, though the name is a discrete transistor code.

Carrying only the part number 2SD1885, this 93.4 KB PDF is filed as a schematic, though it reads as a transistor datasheet by name.

A 90.1 KB PDF named after the 2SD1877 semiconductor and filed as a schematic, although its content is expected to be a component datasheet.

Datasheet-style PDF for the 3SK264, roughly 82.2 KB, indexed as a schematic. The name contains only the type number.

Component documentation for the 3N246, a 43.6 KB PDF indexed as a schematic. The name follows the JEDEC 3N numbering used for four-terminal semiconductor devices, and…

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.

Indexed in the schematic category, this 141 KB PDF is named for the 2SK2792. Japanese JIS numbering uses 2SK for N-channel field-effect transistors, pointing to a…

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…

The 2SK2598 is documented in this 418 KB PDF, listed among schematics but named only by part number, which indicates a component datasheet.

Specification PDF of 34.9 KB for the 2sk2577, grouped under schematics although the name is a plain part number.

Compact 65.7 KB PDF for the 2SK2539, listed as a schematic but named after a discrete semiconductor.

Covering the 2SK2507, this 422 KB PDF belongs to the JIS family of N-channel field-effect transistors denoted by the 2SK prefix.

Sized at 111 KB, a PDF for the 2SK2394 that the index lists under schematics, though its JIS-style part number indicates a datasheet for an N-channel field-effect…

Reference PDF for the 2SK2151 N-channel field-effect transistor, about 96 KB and catalogued as a schematic, though a part-number name like this normally means a…

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 2SK1867 is named in this small 33.9 KB PDF, catalogued under schematics. Because 2SK is the Japanese prefix for N-channel field-effect transistors, expect a brief…

A 295 KB PDF on the 2SK1825 semiconductor. The 2SK prefix follows the JIS standard for N-channel FETs, suggesting a datasheet despite the schematic category.

Short 36.3 KB PDF on the 2SK1803. Part numbers prefixed 2SK are N-channel field-effect transistors in the Japanese JIS registration system, and this file is most likely…

Part datasheet in PDF form for the 2SK1727, about 86 KB. Its 2SK prefix marks an N-channel FET under the Japanese transistor naming system; manufacturer, package and…

Compact 90.8 KB PDF identified only by the code 2SK1469. In Japanese semiconductor numbering, 2SK stands for an N-channel FET, so the schematic tag aside, this should be…

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.

Data for the 2SK1443 in a 110 KB PDF, indexed as a schematic though it is presumably the transistor's data sheet.

PDF for the 2SK1053 transistor, 107 KB, filed as a schematic but by its name a single-part datasheet.

A 32.0 KB PDF for part 2SJ616, placed among schematics but named like an individual transistor datasheet.

The 2SJ287 is covered in this 96.7 KB PDF. Only the part number is present in the name, so no equipment details can be given.

Named after the 2SJ190, this 93.3 KB PDF sits in the schematic category but, given the JIS 2SJ prefix for P-channel field-effect transistors, should contain the…
