Duplicate of the BC328 PNP transistor document, rated minus 30 V and minus 800 mA per the name, in a 53.5 KB PDF identical in size to its companion copies.

Named after the 2SD2282, this 129 KB PDF is most likely the transistor's datasheet, despite the schematic classification in the index.

A 100 KB PDF whose name is simply the part number 2SC4171; despite the schematic label it is best treated as a transistor datasheet.

This 129 KB PDF, named 30WQ06FN and filed as a schematic, appears to document a single semiconductor, most likely a Schottky rectifier in a surface-mount package, rather…
