PDF of 129 KB for the 2SD1427, an NPN bipolar transistor in the 2SD series, indexed as a schematic but most likely a datasheet. The name gives no ratings or package.

The 2SD1829 is covered by this 154 KB PDF, filed under schematics although the name points to a discrete transistor datasheet.

Short 28.1 KB PDF for the 2SD2627, catalogued as a schematic though it is most likely a brief datasheet.

Short 26 KB PDF named 5HN01SS, filed as a schematic yet describing a single small component. The SS suffix likely marks the most compact package in the 5HN01 range.

The 2SD2129 transistor is documented in this 216 KB PDF datasheet, catalogued among schematics.

Brief 29.5 KB PDF identified as 2sj163. In the Japanese JIS scheme the 2SJ prefix marks a P-channel field-effect transistor, so the content is probably a short datasheet…

PDF of 135 KB for the 2SC5277, filed as a schematic but most likely a transistor datasheet, as 2SC is the JIS prefix for NPN bipolar devices.

Datasheet for the 2SC4600 transistor, a 115 KB PDF filed within the schematic category.

2SC4317 is the sole identifier in this 468 KB PDF, listed as a schematic but most likely the component datasheet.
