Covers the 2SD1826 in a 152 KB PDF; the index labels it a schematic, but a bare part number like this normally means a component datasheet.

Titled in lowercase as 2sd1414, this 62.9 KB PDF is catalogued as a schematic, though a lone part number indicates a transistor datasheet.

Indexed as a schematic, the 217 KB PDF 2SD1412A most likely holds the datasheet for that transistor, where the A suffix marks a variant of the 2SD1412.

Covering the 2SD1619, this 123 KB PDF appears in the schematic category, although a part-number title indicates a datasheet.

Stored under schematics, this 171 KB PDF is named 2SD1407A and is most probably the datasheet for that transistor variant, the A suffix distinguishing it from the base…

A 107 KB PDF titled with the lowercase part number 2sd1565, catalogued as a schematic yet almost certainly a transistor datasheet.

Part documentation for the 2SD1631, a 162 KB PDF listed as a schematic. JIS designation 2SD indicates an NPN bipolar transistor designed for low-frequency or power…

Listed as a schematic, this 89.6 KB PDF is named 2SD1883 and is most likely the corresponding transistor datasheet rather than a circuit drawing.

PDF reference sheet for the 2SD1682 transistor, 150 KB, stored in the schematic category.

Reference document for the 2SD1662 transistor, 137 KB, PDF format, placed in the schematic category.

The 2SD1622 PDF, 138 KB in size, sits among schematics, but a file named only by a semiconductor part number is very likely the device datasheet.

Part 2SD1411A gives its name to this 217 KB PDF, sorted into schematics though it is almost certainly a component datasheet; the A suffix indicates a variant of the…

The 2SD1409A file is a 212 KB PDF listed among schematics; a name made only of a part number strongly suggests a datasheet, and the A suffix denotes a variant of the…

Indexed as a schematic, the 2SD1723 PDF of 146 KB is a component sheet for one discrete transistor.

Datasheet-style document, 133 KB in PDF format, covering the 2SD1681 part number and listed as a schematic.

A compact 30.6 KB PDF tied to the 2SD1666 part number, catalogued among schematics. In Japanese JIS designations, 2SD stands for an NPN bipolar transistor meant for…

Transistor sheet for the 2SD1626, 87.9 KB in PDF format, filed as a schematic. In JIS codes, 2SD denotes an NPN bipolar device for low-frequency or power circuits.

Very small 22.2 KB PDF relating to the 2SD1999, filed as a schematic. The name offers nothing but the part code, which follows the JIS scheme where 2SD denotes an NPN…

Brief 29.4 KB PDF for the 2SD1555, held in the schematic section, though the name is just a part number and likely belongs to a datasheet.

An 88.2 KB PDF titled 2SD1884, indexed in the schematic section but, judging by the bare part number, a datasheet for that transistor.

A 100 KB PDF for the 2SD1685, categorised as a schematic but named in the manner of a single-part datasheet.

Named for the 2SD1618 transistor, a 116 KB PDF listed as a schematic but most plausibly the part's datasheet.

PDF of 184 KB bearing the part number 2SD1410A, kept in the schematic category but best treated as the transistor's datasheet, with the A suffix denoting a variant of…

Carrying only the part number 2SD1885, this 93.4 KB PDF is filed as a schematic, though it reads as a transistor datasheet by name.

A 90.1 KB PDF named after the 2SD1877 semiconductor and filed as a schematic, although its content is expected to be a component datasheet.

Part reference for the 2SD1669, supplied as a 107 KB PDF and filed in the schematic section.

Transistor documentation for the 2SD1667, 136 KB in PDF format. Nothing beyond the part number appears in the name.

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.

Part number 2SD1424 with an unexplained _E suffix names this 41.4 KB PDF, indexed among schematics but most likely a datasheet for the transistor.

Component documentation for the 2SD1881 transistor, supplied as a 90.6 KB PDF and catalogued as a schematic, though a part number like this normally points to a…

Filed as a schematic, this 44.1 KB PDF carries the name 2SD1450 with an _E suffix that the name does not explain; the part number points to a datasheet.

PDF document of 49.5 KB named 2SD1996 followed by an E tag, filed under schematics. The 2SD prefix is the Japanese JIS designation for an NPN bipolar transistor, so this…

The 2SD1879 is documented in this 94.5 KB PDF, indexed as a schematic yet most likely a manufacturer datasheet for the part.
