Single-part PDF of 47.0 KB for the 2SD2583, listed as a schematic but most probably a datasheet.

Part number 2SD2459 names this 41.2 KB PDF, followed by an unexplained E tag; it is catalogued as a schematic.

The 2SD1511 NPN transistor is the subject of this 56.9 KB PDF, filed under schematics in the index. JIS numbering assigns 2SD to low-frequency NPN bipolar parts.

For the 2SK3411 transistor, this 32.0 KB PDF provides the component reference, even though the index files it as a schematic.

Reference PDF for the 2SK2714 transistor, 144 KB, filed in the schematic section. JIS naming uses 2SK for N-channel field-effect transistors, so the contents should be a…
