Datasheet PDF, 64.6 KB, for the KA7500B, a PWM control IC from the KA7500 series and a TL494-style design widely found in computer power supplies.

PDF covering the BF458 and BF459 transistors, a compact 49.2 KB file listed as a schematic but most likely a shared datasheet.

Part documentation for the 2SD2615, filed under schematics but by its name a component datasheet rather than a board drawing.

A 43.6 KB PDF for the 3N247, filed among schematics but named after a discrete component, so it is most likely a datasheet.

The 2SD2285 is documented in this 128 KB PDF. Its JIS part number, with the 2SD prefix, places it among NPN transistors intended for low-frequency circuits such as…

A 116 KB PDF associated with the 2SD2284 NPN transistor, a part numbered under the Japanese JIS standard, where 2SD denotes NPN low-frequency types.

The 2SD1907 is covered by this 165 KB PDF, which is catalogued as a schematic but by name is a component datasheet.

Covering the 2SK2910 transistor, this 150 KB PDF is listed in the schematic category but reads from its name as a component datasheet.

The 2SK545 is covered by this 80.4 KB PDF, filed as a schematic but most likely a datasheet because 2SK numbers identify N-channel field-effect transistors in the…

The 2SK427 document is a 226 KB PDF filed as a schematic, but the 2SK prefix marks an N-channel field-effect transistor in the JIS numbering scheme, so it is effectively…

A 140 KB PDF named after the semiconductor 2SJ563, listed in the index under schematics.

Datasheet-style document for the 2SJ537, delivered as a 137 KB PDF though indexed as a schematic.

A compact 44.5 KB PDF labelled 2SJ520 and catalogued as a schematic. Because 2SJ is the JIS prefix for P-channel FETs, the document is best treated as a short datasheet…

The name of this 97.3 KB PDF gives nothing beyond 2SJ277, a JIS-style designation in which 2SJ marks a P-channel FET.

Only the part number 2SJ275 appears in the name of this 97.0 KB PDF. That code follows Japanese JIS numbering, where 2SJ indicates a P-channel field-effect transistor…

Filed as a schematic, this 93.5 KB PDF is identified solely by 2SJ274. The Japanese JIS 2SJ prefix stands for a P-channel field-effect transistor, so the content is most…

Named after the JIS part number 2SJ267, this 91.8 KB PDF most likely documents a P-channel field-effect transistor, since the 2SJ prefix denotes that device class.

Indexed as a schematic, this 79.2 KB PDF is named 2SC4400 and should be the reference datasheet for that NPN bipolar transistor.

Listed under schematics but named only after a part number, this 91.6 KB PDF most likely holds the datasheet for the 2SC4188 transistor.

The 2SC4121 part number is the whole name of this 89.5 KB PDF; although typed as a schematic, it should be the datasheet for that NPN bipolar transistor, as the Japanese…

A PDF document for the 2SC4884, filed under schematics but by its name a component datasheet rather than a board diagram.

The 2SC5777 is covered by this small 29.9 KB PDF, catalogued as a schematic but most likely a single-part datasheet.

PDF of 37.3 KB named after the 2SC5406 and listed as a schematic, though it is almost certainly a component datasheet.

Part documentation for the 2SC5302 in PDF form, 89.2 KB, placed in the schematic section of the index.

A brief 48.3 KB PDF on the 2SC3504, catalogued as a schematic but containing transistor data.

Compact 49.5 KB PDF for the 2SC3354, with an _E suffix in the name that may indicate an English-language edition, though the name does not confirm it.

PDF of 61.5 KB for the 2SA1870, with a 1-2 tag in the name. That tag may indicate one part of a split document or a revision, but the name does not say which.

PDF, 52.3 KB, documenting the 2SA1177, a PNP bipolar transistor in the JIS 2SA numbering scheme.

The 2SA1734 is the subject of this 183 KB PDF, which carries only the component number in its name.

A compact PDF of 48 KB filed under schematics, named after the part 2PB1219A with a trailing 3 that probably marks a document issue.

Short PDF document, 47.9 KB, whose name points to the component 2PB710A, with the suffix 6 likely indicating a revision of the sheet.

PDF of 25.8 KB carrying only the code 2pg302 in its name and filed under schematics. No laptop model, board number or manufacturer is stated, so the content cannot be…

PDF of 47.7 KB named 2PD602A, apparently issue 4 of the document. The name identifies a part rather than a product or board, which points to a discrete semiconductor…

PDF of 168 KB filed as a schematic and named 2N2219A, a designation in the JEDEC 2N numbering used for discrete semiconductors.

A small 26.9 KB PDF in the schematic category, named only with the part number 2N6519 from the JEDEC 2N registration series.

Reference sheet in PDF form covering the 1SV214, filed under schematics although at 75 KB it reads like a single-part data sheet.
