The 3LP02SP part is documented in this 41.9 KB PDF, catalogued under schematics. The name gives only the component code; companion files 3LP02N and 3LP02M share the…

Small 23.4 KB PDF for the 2SK2660 transistor. The 2SK designation comes from the Japanese JIS system for N-channel FETs, so the file is most likely a brief datasheet…

Small 101 KB PDF named for the 2SK2441, indexed as a schematic though the part number style suggests a component datasheet.

Very small 32.3 KB PDF titled 2SK2383, listed in the schematic category but most probably a short datasheet or summary sheet for an N-channel field-effect transistor, as…

The part number 2sk2210 is the sole clue to this 33.6 KB PDF, catalogued under schematics but most likely a short component datasheet.

Small PDF document, 28.8 KB, identified only by the part number 2SJ615 and filed as a schematic.

Small 98.3 KB PDF for the 2SC5300 part. The 2SC prefix is the Japanese JIS registration for NPN bipolar transistors, so despite being listed as a schematic, the file is…

The 2SC5226 is covered by a 112 KB PDF that the index classes as a schematic, though the name indicates a component datasheet.

Small 41 KB PDF for the 2SC5190, with an _E suffix that may denote an English-language edition, though the name does not state this.

Named 2SC4599, this 129 KB PDF is filed with schematics but reads as a part-number datasheet for a JIS-designated device, where 2SC means an NPN bipolar transistor for…

At 411 KB, this PDF for the 2SC5717 is one of the larger documents in the set and is probably a complete datasheet with graphs.

Small 39.5 KB PDF for the 2SA1791, indexed as a schematic but named after a JIS PNP bipolar transistor, which points to a component datasheet.

Small 45.8 KB PDF dedicated to the 2N3866, sorted into the schematic section of the index though the name indicates a discrete component datasheet.

Datasheet-style PDF for the 1SS385F, 68.1 KB, filed under schematics. The trailing F is part of the part number and may indicate a package or variant of the 1SS385, so…
