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.

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.

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.

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.

At just 33.5 KB, this PDF for the 2SD1623 is a short document listed as a schematic, though the part-number name suggests a compact datasheet.

A 115 KB PDF named after the 2SD1625 part number, catalogued as a schematic but in practice most likely the transistor's datasheet.

PDF of 77.6 KB named 2SD1620 and filed with schematics; the name carries nothing beyond the part number, which points to a component datasheet.

Document for the 2SD1624, a PDF of 144 KB stored in the schematic section; with only a part number in the name it should be treated as a datasheet.

BIOS image for the Dell Latitude 3480 on Wistron board 16852-1, also marked with Dell part number D5FVH.
