Datasheet-style PDF for the 5LP02SP, about 42.2 KB and placed in the schematic category.

PDF covering the 3SK189, about 178 KB in size and listed in the schematic category, though the name points to a single component datasheet.

Part reference for the 3N250, stored as a PDF of about 43.6 KB and catalogued in the schematic section.

A 416 KB PDF covering the 2SK2610, a JIS-designated part whose 2SK prefix identifies an N-channel FET.

A 34.3 KB PDF for the 2SK1846 transistor. The 2SK prefix follows the Japanese JIS convention for N-channel FETs, so this is probably a part datasheet even though it is…

PDF of about 295 KB for the 2SK1827. In JIS part numbering, 2SK stands for an N-channel FET, so the content should be a datasheet rather than a board-level drawing.

Compact 42 KB PDF for the 2SJ340, catalogued among schematics although the name is a transistor part number. Nothing else about a device or board is stated.

Part-number reference for the 2SC4433 in PDF form, about 71.5 KB. The name gives no board or device, only the JIS designation, where 2SC denotes an NPN bipolar…

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

Indexed as a schematic, this 195 KB PDF carries just the type number 2SC3803. In JIS semiconductor naming, 2SC stands for an NPN transistor, so the content is most…

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…
