Small 29.3 KB PDF covering the 2SA1436 transistor. In the Japanese JIS designation system a 2SA number denotes a PNP transistor, nominally a high-frequency type, though…

Brief 41.1 KB PDF for the 2SA921, with an _E suffix in the name that likely marks an English-language edition, though that is not certain.

Component sheet in PDF format, 47.7 KB, named for 2PC4081, probably revision 4 of the document.

At only 23.6 KB, this PDF named 30WQ04FX is probably a brief datasheet or ordering note for a discrete rectifier, despite being indexed as a schematic.
