Reference PDF for the 2SK620, a JIS-series N-channel field-effect transistor, weighing 35.6 KB and listed under schematics though it is most likely a datasheet.

The 2SC4163 part number is all this 98.9 KB PDF name reveals, so although labelled a schematic it is best read as a transistor datasheet.

Named in lowercase for the 2sc4132, this 63.0 KB PDF is classed as a schematic but is better understood as the datasheet for an NPN bipolar transistor, which is what the…

The 2SC5323 is the only clue in this file name, so treat this 122 KB PDF as a probable transistor datasheet even though it sits in the schematic category.

This 145 KB PDF carries only the part number 2SC2884 in its name and is filed as a schematic.

Catalogued among schematics, this 54.5 KB PDF is named for the 2SB642, which the JIS 2SB prefix marks as a PNP transistor; the document is therefore expected to be a…

Covering the 2SA1433, this 78.1 KB PDF is indexed as a schematic but is most likely a component data sheet.

At 245 KB, this PDF for the 2SA1721 is one of the larger documents in the series, suggesting several pages of curves or package data.

Covering the range 5KP5.0 to 5KP110A, this 667 KB PDF is filed as a schematic but is named after a component series rather than a device or board.

The 80RIA name on this 191 KB PDF refers to a series of power semiconductors rather than a circuit board, and although it is filed as a schematic, a component datasheet…
