Large 962 KB PDF for the LM324P, the quad operational amplifier in a plastic DIP package, as the P suffix commonly indicates.

At 312 KB, this PDF for the 2SD2638 is the largest in its series and is probably a full datasheet with curves and outline drawings, though it is filed under schematics.

Reference sheet in PDF form, 141 KB, for the 2SD2198 transistor. The file is indexed as a schematic but is most likely a datasheet.

Small 27.4 KB PDF named after the part code 5LN01C, indexed as a schematic though it reads like a discrete-component datasheet.

Small 39.9 KB PDF for the 2SD2474, carrying an _E suffix whose meaning the name does not state; it may reflect a language or edition marker.

PDF of 43.6 KB for the 3N252, listed under schematics though the name is a bare JEDEC part number.

Filed under schematics, the 39.8 KB PDF 2SD2441 with an E tag refers by its JIS-style 2SD prefix to an NPN bipolar transistor.

A 365 KB PDF for the 2SK2859, filed under the schematic type though it is most probably a manufacturer datasheet. Nothing other than the part number appears in the name.

Small 30.0 KB PDF covering the 2SK2047 transistor. Under the JIS naming system the 2SK prefix marks an N-channel FET, so this is best treated as a part datasheet rather…

A compact 32 KB PDF named 2SK1447LS, filed as a schematic. It appears to cover a variant of the 2SK1447 carrying an LS suffix, whose meaning the name does not explain.

Filed under schematics, the 143 KB PDF named 2SJ509 most probably holds the datasheet for a single transistor, since 2SJ in the Japanese JIS scheme designates a…

The 2SJ339 appears in this small PDF of roughly 40.7 KB. The name carries only the part number, with no hint of the equipment it came from.

Specification PDF, roughly 32 KB, for the 2SD667 transistor, listed among schematics but in fact a component datasheet.

Datasheet-style PDF of 44.0 KB for the 2SC4391, filed as a schematic; the trailing _E suffix in the name is not explained and could denote an edition or language…

Indexed as a schematic, this 91.5 KB PDF named 2SC4390 is most likely the datasheet of that NPN bipolar transistor.

Part number 2SC4157 is the only clue in the name of this 125 KB PDF, which sits under schematics but is effectively a transistor datasheet.

Covering the 2SC5028, this 219 KB PDF is filed as a schematic yet is named like a component datasheet.

Reference PDF, 99.3 KB, for the 2SC3994, listed in the schematic category but named like a transistor datasheet.

Datasheet PDF for the 2SC3931, 60.7 KB, with the _E suffix common to this group of files and listed as a schematic.

Small 41.6 KB PDF for the 2SC5388, a JIS-numbered NPN bipolar transistor; the file name states only the part number, so package, maker and application are not given.

Indexed as a schematic, this 95.8 KB PDF carries only the designation 2SC4821. In the JIS system the 2SC prefix denotes an NPN transistor, so the content is most likely…

Named for the 2SC2995, this 510 KB PDF is listed as a schematic but most likely holds the datasheet for a JIS-numbered NPN transistor, as the 2SC prefix indicates.

Filed under schematics, this 80.8 KB PDF is titled with the part number 2SC2857. The JIS 2SC prefix designates an NPN bipolar transistor, so the content is most likely a…

Named after the JIS part number 2SC2816, this 50 KB PDF appears in the schematic category but most likely contains the datasheet of an NPN bipolar transistor, as the 2SC…

A compact 33.0 KB PDF named for the 2SB647, a PNP transistor according to the JIS 2SB prefix; although indexed as a schematic, it is most likely the part datasheet.

Component datasheet for the 2SB1644, a small 48 KB PDF catalogued under schematics. JIS numbering places any 2SB part among PNP bipolar transistors for low-frequency…

Small 39.6 KB PDF containing the datasheet for the 2sb1616, catalogued as a schematic entry.

Datasheet PDF covering the 2SA1588, 215 KB in size, which suggests several pages with curves and package details.

The 2SA1572 transistor is documented in this 49.4 KB PDF. No board or equipment model appears in the name, so treat it as a component datasheet.

Datasheet PDF for the 2SB1274, 34.4 KB in size and likely a concise sheet. The name offers only the part number.

PDF document for the 2SA1200, a part number in the Japanese JIS 2SA series, which designates PNP bipolar transistors.

PDF of 46.9 KB filed under schematics but named after the component 2PC4617, with a suffix 3 that likely denotes the document issue.
