Reference sheet in PDF for the RJH60F7, an IGBT the file name rates at 50 A and 600 V. Devices of this type turn up in induction heating appliances, inverter welders and…

PDF for the CEP540N transistor, with the name noting 100 V and 36 A ratings, about 626 KB in size.

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 name 3LP01S identifies this 28.1 KB PDF only by a component-style code with an S suffix; no laptop, board number or revision appears.

Short 28.6 KB PDF filed under schematics with the name 3LP01N, a code that resembles a discrete semiconductor part number with an N suffix.

Listed as a schematic, this PDF of 28.2 KB is named 3LP01M and carries nothing beyond that part-style code with an M suffix.

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.

A 55.2 KB PDF named after the 2SK2348, a JIS-registered type whose 2SK prefix indicates an N-channel FET.

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.

Named simply 2SJ226, this 84.5 KB PDF refers to a JIS-registered P-channel FET and most likely contains the part datasheet, even though it sits in the schematic section.

PDF reference, around 129 KB, covering two power ICs identified by marking codes: Qq for the SY8386BRHC and 3a for the SY8388C3RHC.

Schematic set for the Xiaomi POCO M3 in PDF form, packed inside a 4.20 MB RAR archive. Once extracted it opens in any PDF reader and lets a technician search for net…

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

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.

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.

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