Reference sheet for the 2SB1184, a part number in the Japanese JIS series where 2SB indicates a low-frequency PNP bipolar transistor.

The 130 KB PDF titled 2SD1348 relates to a JIS-numbered NPN bipolar transistor, the 2SD series covering low-frequency types, and is expected to be a component datasheet…

Covering the 2SD1246, this 85.2 KB PDF is filed among schematics but its name is simply a JIS transistor number.

The 466 KB PDF here is titled only 2SC4841, a Japanese JIS transistor code where 2SC stands for NPN.

Reference datasheet for the 2SB1617 PNP transistor, supplied as a 213 KB PDF. Following Japanese JIS numbering, 2SB parts are PNP bipolar transistors for low-frequency…

A 27 KB PDF named 5HN01M, filed under schematics but referring to a single discrete component. The M suffix most likely denotes a package within the 5HN01 series.

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

A 398 KB PDF for the 2SK2034, a part in the Japanese 2SK series of N-channel field-effect transistors.

Datasheet for the 2SD1187 transistor in PDF form, 227 KB, which is larger than most sheets in this series and may include more curves or package options.

The 2SA1587 transistor is the subject of this 323 KB PDF, the largest in this group and likely to include detailed characteristic graphs.

Datasheet in PDF format for the BD244C, judging by the name, a small 137 KB document. BD244-series parts are generally PNP power transistors in TO-220 packages, and the…
