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

Part documentation for the 2SK2628LS, a 28.6 KB PDF. The 2SK prefix places it in the Japanese JIS family of N-channel field-effect transistors, and the LS suffix denotes…

A 322 KB PDF datasheet for the 2SK2613, indexed under schematics. The 2SK prefix is the Japanese JIS registration for N-channel FETs, and the file size points to a…

Here the 2SK1730 is documented in a 97.1 KB PDF. The 2SK prefix belongs to the Japanese JIS/JEITA register and indicates an N-channel field-effect transistor, so the…

The 2SK1237 N-channel transistor is the subject of this 45.8 KB PDF, filed under the schematic category.

PDF reference for the 2SD1160, about 220 KB, indexed as a schematic although the file name names only a transistor part.

Covering the plain 2SC5261 without suffix, this 183 KB PDF is indexed as a schematic but concerns a single NPN bipolar transistor, as the JIS 2SC prefix indicates.

Datasheet PDF for the 2SC5229, 135 KB, kept in the schematic category of the index. Japanese JIS part numbering assigns 2SC to NPN bipolar transistors, which identifies…

Larger than most in this series at 211 KB, the PDF for 2SC4448 may include characteristic graphs alongside the ratings tables.

A 200 KB PDF for the 2SC5458, a part in the Japanese 2SC numbering scheme for NPN bipolar transistors, filed here as a schematic.

Part 2SC5048 is the only detail in the name of this 210 KB PDF, classed here as a schematic.

Datasheet-style PDF, 42.2 KB, for the 2SC3829 transistor, carrying an _E suffix whose meaning the name does not explain, possibly an edition or language tag.

Datasheet PDF for the 2SC3311A, the A suffix denoting a variant of the base 2SC3311 number, filed under schematics at 40.5 KB.

A 308 KB PDF named after the 2SC2753 semiconductor and placed in the schematic section.

Named after the 2SA1527 transistor, this 30.7 KB PDF appears in the schematic category though its content should be the datasheet for the part.

PDF documentation, 75.9 KB, for the 2SA1434 transistor. Under the JIS scheme the 2SA prefix denotes a PNP transistor, and no other variant, maker or package information…

For the transistor 2SA2039 this 40.2 KB PDF most likely provides the manufacturer datasheet, even though it sits in the schematic category.

Datasheet-type PDF for the 2SA1964 PNP transistor, 38.5 KB, named with the lowercase part code only.

Datasheet PDF for the 2SA1048, with an L in brackets in the name that probably refers to a gain rank or variant, though this is not explained.

Datasheet for the 2SA1811 in PDF format, 173 KB in size, filed alongside schematics in the catalogue.

A 171 KB PDF catalogued as a schematic for the 2N6379, with an RE suffix not defined by the file name.

Datasheet-style PDF for the 2N5089, listed in the schematic category at 97.4 KB. The name gives just the JEDEC part number, with no maker or revision stated.

A 255 KB PDF for the 2N4918, tagged RE in the name, possibly a revised or alternate edition though this is not defined.

Datasheet for the 2N3392 in a 296 KB PDF, filed as a schematic. Identical in size to neighbouring 2N3390 to 2N3393 entries, it is probably a shared family document…

Brief 45.2 KB PDF covering the 183NQ series, a Schottky rectifier family whose name lacks a voltage suffix, so several grades are probably tabulated together.

The 154 KB file 93CXXXX.pdf is indexed as a schematic, but the wildcard name points to a datasheet covering a range of 93C-series Microwire serial EEPROMs.

A 148 KB PDF named 27lc512, filed under schematics but most likely a datasheet for a low-voltage 27-series EPROM, given how the part number is built.

Parallel flash datasheet, 174 KB PDF named 29F080 and filed under schematics. The 29F080 designation is commonly used for 8 Mbit parallel NOR flash memory; the name…

Schematic in PDF format for the X51C, carrying an extra T12C tag that probably identifies a board or project code, though the name does not say so. The file is 1.58 MB.

Spanish microelectronics course in PDF form, 4.14 MB, without any specific device, brand or board named.
