Component data for the 2SD2130 NPN transistor, a PDF of about 209 KB. The name carries no board or device information; it is a part sheet following the Japanese 2SD…

Datasheet for the 2SD2117, filed as a schematic but actually a component specification in PDF form, about 67.5 KB.

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

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.

One of the larger sheets in the set at 271 KB, this PDF is named after the 2SD2498 and serves as a transistor datasheet.

The only detail in this 183 KB PDF name is the part number 2SD2461, indicating the datasheet for that transistor.

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

This 145 KB PDF carries the 2SD1722 part number and nothing more, so it is best treated as that transistor's 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…

PDF reference, 67.1 KB, for the 2SD1627 transistor, stored in the schematic section. The name carries nothing besides the part number.

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 53.3 KB PDF for the 2SD2071, with an E suffix in the name whose meaning is not stated.

Covering the 2SD2067, this 60 KB PDF carries an E suffix that the name leaves unexplained.

Larger 185 KB PDF for the 2SD2012, written in lowercase in the name and placed among schematics.

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.

PDF documentation, 32.7 KB, for the 3SK269, indexed under schematics. The JIS code 3SK marks an N-channel field-effect transistor with four terminals, generally a…

The 3SK263 is covered by an 82.7 KB PDF placed in the schematic category, though a part-number name like this normally indicates a component datasheet.

The 3LP02SP part is documented in this 41.9 KB PDF, catalogued under schematics. The name gives only the component code; companion files 3LP02N and 3LP02M share the…

The 2sd2394 NPN transistor is covered by this 53.3 KB PDF, which the index files as a schematic.

Reference sheet in PDF form (32.2 KB) for the 2SK3414LS, listed in the schematic section of the index.
