Reference PDF for the 2SK1888 N-channel FET, 94.9 KB, catalogued as a schematic. The 2SK code follows the Japanese registration system for transistors, so this is a…

Filed as a schematic, this 372 KB PDF named 2SJ465 most likely holds the full datasheet for a P-channel field-effect transistor, since that is what the 2SJ prefix means…

Compact 53 KB PDF for the 2SC4606, carrying an _E suffix that may mean an English edition, though the name does not say so explicitly.

The 2SA1539 part number gives this 41.0 KB PDF its name, and although it is filed under schematics it almost certainly holds the datasheet for that transistor.

Named simply 50SQ, the 132 KB PDF in the schematic category covers what looks like a component family rather than a specific device; no brand, model or board is given.

Schematic in PDF form, 1.72 MB, named TERESA20. The name carries only what looks like a project code name with no brand, model or board number, so open the file and read…

Samsung SM-M307F service manual section, 1.41 MB PDF; the Direy part of the name is unclear and its exact chapter content is not stated.

An 88.8 KB PDF describing the 2SD1806, filed in the schematic index although it is most likely a part datasheet.

PDF of 59.1 KB labelled only 30BF and listed as a schematic, with no model, brand or board number provided.

This small 31.6 KB PDF bears the name 2SK1444LS and is classed as a schematic. The name links it to a suffixed variant of the 2SK1444 without saying what LS stands for.

At 249 KB this PDF is the largest in the group and covers the 2SA1618, indexed as a schematic but in practice a transistor reference.

Small 30.2 KB PDF for the 2SA1968LS, a variant of the 2SA1968 identified by the LS suffix; what that suffix denotes is not explained in the name and should be confirmed…

Specification sheet for the 1N5393 diode saved as a 42.7 KB PDF and indexed in the schematic category.

Larger 697 KB PDF relating to the 1N4001 rectifier, filed in the schematic category. The double plus in the name gives no clear information, so it may be an extended…
