PDF specification of about 78 KB for the 2SD1799 NPN transistor, named in the Japanese 2SD series and companion in numbering to the neighbouring 2SD1800 sheet.

Datasheet for the 2SD1784 transistor in PDF format, roughly 153 KB, listed among schematics. The 2SD designation marks an NPN low-frequency device under the JIS system.

Part datasheet for the 2SD1782K, an NPN transistor named under the Japanese JIS scheme, with the K suffix indicating a particular variant or package.

Specification sheet in PDF, around 82 KB, for the 2SD1781K NPN transistor of the JIS 2SD series; the K suffix denotes a specific version of the base part.

PDF datasheet of about 125 KB covering the 2SD1766 NPN transistor, part of the Japanese JIS 2SD numbering.

The 2SD1760 NPN transistor is documented in this 77 KB PDF, categorised as a schematic though it is a component datasheet.

Compact 46 KB PDF datasheet for the 2SD1757K, an NPN transistor under Japanese JIS designation, with a K suffix marking its variant.

Filed as a schematic, this 53 KB PDF is named after the 2SD1725 part number, so it is most likely a component datasheet rather than a board diagram.

The 2SD1724 part number is all the name gives, and the 145 KB PDF is tagged as a schematic, though a file named this way is normally a transistor datasheet.

This PDF of about 124 KB covers the 2SD2114 transistor with a KS suffix; the suffix is not explained by the name and may denote a gain class or package variant.

Listed under schematics, the 2SD2100 PDF of 144 KB is in practice a reference sheet for a single discrete part.

The 2SD2099 part number is the only detail in this 126 KB PDF name, which points to a datasheet for a Japanese-coded transistor.

For the 2SD2098 transistor, this 159 KB PDF is categorised as a schematic but follows the usual naming of a part datasheet.

Named after the 2SD2093, this PDF of 146 KB is most likely the component datasheet for that Japanese transistor.

At 242 KB, the 2SD2092 PDF is one of the larger files in this series and carries no information beyond the part number.

Only the part number 2SD2088 appears in the name of this 171 KB PDF, so treat it as the datasheet for that transistor.

The 2SD2079 PDF, 219 KB in size, is indexed as a schematic yet corresponds to a single discrete component.

This 244 KB PDF covers the 2SD2075A; the trailing A marks a variant of the base 2SD2075 type, though the name does not say how it differs.
