Datasheet-style PDF for the BU2508DX, roughly 80 KB, indexed under schematics. This is a well known horizontal deflection transistor for CRT TVs and monitors, and the D…

Catalogued as a schematic, this 27.2 KB PDF carries only the code 3LP01SS, which looks like a component part number with a two-letter SS suffix.

The name 2sd1455 refers to a JIS-registered NPN transistor, and this 53.0 KB PDF is most likely its manufacturer datasheet, although the index lists it as a schematic.

A compact 23.3 KB PDF for the 2SK2772, an N-channel FET according to the JIS 2SK naming convention, catalogued here as a schematic.

Compact 33.0 KB PDF on the 2SK1834 transistor. The 2SK prefix belongs to the Japanese JIS designation system and means an N-channel field-effect device, so the content…

The name 2SK1446LS marks this 32 KB PDF as covering an LS-suffixed version of the 2SK1446.

At just 31.4 KB, the PDF named 2SJ499 is probably a short datasheet or summary sheet, even though it is filed as a schematic.
