A 194 KB PDF describing the 2SD2604A, listed as a schematic but most likely a transistor datasheet.

Reference PDF of 40.9 KB for the 2SD1819A, with an E tag in the name that probably denotes an English-language edition, filed under schematics.

A 28.0 KB PDF classed as a schematic whose name, 3LP01C, reads as a component part code ending in C. The file name gives no device, board number or manufacturer.

Filed as a schematic, the 28.3 KB PDF 3LN02SP is named after what appears to be a discrete component code, here from the LN series with an SP suffix.

PDF of 41.6 KB, catalogued as a schematic and named 3LN02M, which looks like a semiconductor part number with an M suffix rather than a board code.

PDF of 27.9 KB filed as a schematic under the code 3LN01S, which reads as a discrete component part number with an S suffix.

Reference sheet for the 2SK2917 N-channel field-effect transistor, stored as a 423 KB PDF and listed in the schematic category.

Datasheet PDF of 413 KB for the 2SK2866 transistor, catalogued under the schematic type. Only the part number is stated in the name.

PDF of 140 KB for the 2SK2739 with an unexplained 1-5 suffix, which may indicate an edition or page count rather than a different part.

PDF reference, 35.6 KB, for the 2SK2276, a Japanese JIS-registered device where the 2SK prefix indicates an N-channel field-effect transistor.

Short 23.7 KB PDF for the 2SK2014, a part number from the JIS 2SK series used for N-channel FETs.

The 2SK690 is named here, and the 2SK prefix marks a Japanese-registered N-channel FET, so this 32.6 KB PDF is best treated as a part datasheet even though it is filed…

Part reference 2SJ508 is all the name provides for this 136 KB PDF, categorised as a schematic.
