Reference for the Atmel AT45DB041B, a 4-megabit serial DataFlash memory as the name states, in a 233 KB PDF.

Documentation for the 2SD2599, a 251 KB PDF catalogued among schematics, larger than many single-part sheets and possibly containing characteristic curves and package…

A 40.8 KB PDF giving data on the 2SD2629, stored in the schematic category. Only the part number is present in the name.

Documentation for the 2SD1802 in a 150 KB PDF, filed as a schematic though the name suggests a transistor datasheet.

PDF sheet of about 41.1 KB for the 5LN02M, filed under schematics. Only the part code appears in the name; by the naming pattern LN likely marks the N-channel MOSFET…

PDF of about 41.4 KB covering the 5LN01S, catalogued as a schematic but most likely a component datasheet.

Part 5LN01N is described in this 27.9 KB PDF, placed in the schematic section. The name gives nothing beyond the part code; within this family LN appears to indicate an…

Listed under schematics, the 2SD2100 PDF of 144 KB is in practice a reference sheet for a single discrete part.

The 2SD2099 part number is the only detail in this 126 KB PDF name, which points to a datasheet for a Japanese-coded transistor.

A 167 KB PDF identified only by the 2SD2481 part number, which points to the datasheet for that transistor rather than a board schematic.

Filed as a schematic, this 44.1 KB PDF carries the name 2SD1450 with an _E suffix that the name does not explain; the part number points to a datasheet.

Reference material for the 3SK272 in a 30.2 KB PDF, filed under schematics. The name carries no detail other than the type number.

Datasheet-type document for the 3N251 in a 43.6 KB PDF, indexed as a schematic. JEDEC uses the 3N prefix for registered four-terminal semiconductor devices, and this…

Indexed as a schematic, the 305 KB PDF named 2SK208 most likely holds the datasheet for that Japanese JIS-numbered part.

Named after the JIS designation 2SK184, this 307 KB PDF is tagged as a schematic but is most likely the device datasheet.

A 32.0 KB PDF covering the 2SK3415LS transistor, catalogued as a schematic though it reads as a part datasheet. Under JEITA naming, 2SK marks an N-channel FET.

The 2SK2915 is covered by this 434 KB PDF, indexed under schematics but most likely a component datasheet, since the name carries only the transistor number.

Named solely for the 2SK2777, this 425 KB PDF is catalogued as a schematic but most likely contains the component datasheet.

Specification document, 405 KB in PDF form, for the 2SK2604 transistor. Japanese JIS part numbering assigns the 2SK prefix to N-channel field-effect transistors; beyond…

Covering the 2SK2603, this 410 KB PDF is indexed as a schematic but carries only a component number, pointing to a datasheet.

A 34.5 KB PDF for the 2sk2579, indexed with schematics but named only by part number, so it is most likely a compact component datasheet.
