A 16.0 MB binary whose name suggests a cleaned Management Engine image, though no device, brand or board number is given. The size fits a 128 Mbit SPI flash.

Datasheet PDF, 137 KB, for the 2SD1841, part of the Japanese 2SD range of NPN bipolar transistors, catalogued here under schematics.

An 88.0 KB PDF for the 2SD1838, a Japanese-registered NPN bipolar transistor, best treated as a datasheet even though it is indexed as a schematic.

English-language datasheet, as the _E suffix suggests, for the 2SD2260 NPN bipolar transistor, supplied as a 45.3 KB PDF in the schematic section.

Reference sheet for the 2SD2116 NPN transistor, supplied as a 74 KB PDF. Its name follows the Japanese JIS 2SD convention and carries nothing beyond the part number.

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.

PDF document for the 2SD2028, 91.1 KB, filed in the schematic category. Only the part number is given.

Part documentation for the 2SD1876 in PDF form, 89.6 KB, categorised under schematics. Only the part number is given in the name.

Datasheet PDF for the 2SD1979, filed under schematics at 42.4 KB. The 2SD prefix follows JIS convention for NPN bipolar transistors of the low-frequency class, and the E…

Datasheet PDF of 45.2 KB for the 2SK3280, categorised here as a schematic. The 2SK prefix indicates an N-channel field-effect transistor according to JEITA naming.

A compact 136 KB PDF for the 2SK2989, listed as a schematic yet by name a discrete transistor document. Under the JIS convention 2SK marks an N-channel FET.

A 30.3 KB PDF on the 2SK2659, listed in the schematic section but in practice the documentation of a single N-channel FET, as indicated by the JIS 2SK prefix.

Named only 2SK1463, this 121 KB PDF is grouped with schematics but concerns a discrete part: the Japanese 2SK prefix means an N-channel FET.

Indexed under schematics, this 110 KB PDF carries the part number 2SK1447 and is likely its full component data sheet.

Reference PDF, 110 KB, for the 2SJ383 transistor, catalogued under schematics but by name a datasheet.

At 383 KB, this PDF documents the 2SJ360, indexed as a schematic but by name a transistor datasheet.

The 2SJ312 is documented in this 362 KB PDF, catalogued as a schematic. Beyond the part number the name says nothing about the equipment involved.

PDF of 245 KB titled 2SJ200, which by Japanese JIS convention is a P-channel field-effect transistor; the contents are probably the datasheet rather than a circuit…

Under the schematic category, this 99.0 KB PDF titled 2SJ187 should be the datasheet for a P-channel FET, as the JIS 2SJ prefix indicates.

PDF of 56.2 KB named 2SD1391, a JIS designation for an NPN low-frequency bipolar transistor, and presumably its datasheet although indexed under schematics.

Covering the 2SD1213 transistor, this PDF of 116 KB is indexed under the schematic type.

A 94.8 KB PDF documenting the 2SD895, indexed as a schematic though the name names a single transistor.

The name 2SC4666 identifies a Japanese-registered NPN transistor, and this 262 KB PDF most likely holds its datasheet even though the index lists it as a schematic.

Reference sheet for the 2SC4539, an NPN bipolar transistor by its JIS-style 2SC designation, stored as a 158 KB PDF that any standard PDF reader opens.
