Datasheet for the 5LN01SP in PDF format, roughly 28.0 KB, indexed as a schematic. Only the part number is stated; LN in this series appears to denote an N-channel…

PDF sheet of about 42 KB for the 3N259, catalogued under schematics though the file name is simply a JEDEC part number.

Component sheet covering the 3N254, delivered as a 42.2 KB PDF and indexed as a schematic. JEDEC numbers beginning with 3N denote registered devices having four leads.

PDF for the 2SD1992A NPN transistor, indexed as a schematic though the name points to a part datasheet.

Named 2SK3491, this 29.8 KB PDF is most likely the datasheet for that JIS-numbered device, despite being listed as a schematic.

A compact 30.1 KB PDF for the 2SK2682LS. The base 2SK2682 follows JIS numbering for N-channel field-effect transistors, while the LS suffix marks a variant, often a…

Datasheet PDF of 114 KB for the 2SK2616, a part named under the Japanese JIS scheme for N-channel field-effect transistors.

Specification PDF of 34.9 KB for the 2sk2577, grouped under schematics although the name is a plain part number.

Datasheet PDF of 36.1 KB for the 2sk2572, filed under schematics although nothing in the name points to a board or appliance.
