Datasheet for the BD135 transistor in a 51.0 KB PDF, likely the same family document that also covers related types in the series.

Part documentation for the 2SD2615, filed under schematics but by its name a component datasheet rather than a board drawing.

Short 28.6 KB PDF filed under schematics with the name 3LP01N, a code that resembles a discrete semiconductor part number with an N suffix.

The 2SD2285 is documented in this 128 KB PDF. Its JIS part number, with the 2SD prefix, places it among NPN transistors intended for low-frequency circuits such as…

A 55.2 KB PDF named after the 2SK2348, a JIS-registered type whose 2SK prefix indicates an N-channel FET.

The 2SK427 document is a 226 KB PDF filed as a schematic, but the 2SK prefix marks an N-channel field-effect transistor in the JIS numbering scheme, so it is effectively…

Datasheet-style document for the 2SJ537, delivered as a 137 KB PDF though indexed as a schematic.

A compact 44.5 KB PDF labelled 2SJ520 and catalogued as a schematic. Because 2SJ is the JIS prefix for P-channel FETs, the document is best treated as a short datasheet…

Named after the JIS part number 2SJ267, this 91.8 KB PDF most likely documents a P-channel field-effect transistor, since the 2SJ prefix denotes that device class.
