A 41 KB PDF covering the part coded 5HN02SP, listed with schematics but naming only a component. SP is most likely the package designation in the 5HN02 series.

Reference PDF for the 3N255, sized at 42.2 KB and catalogued among schematics, though nothing beyond the part number is given in the name.

Component documentation in PDF format, 32.4 KB, for the 2SK2326. The 2SK prefix follows the JIS registration scheme and signifies an N-channel FET, so despite the…

A 32.6 KB PDF covering the 2SK2325, a Japanese-registered semiconductor whose 2SK prefix means N-channel field-effect transistor.

Reference sheet for the 2SK2046, supplied as an 88.4 KB PDF. The 2SK designation belongs to the Japanese registration scheme for N-channel field-effect transistors…

Reference PDF covering the 2SK1842, a part number in the JIS 2SK series used for N-channel field-effect transistors.

PDF, 121 KB, for the 2SK1474 transistor. Japanese 2SK numbering denotes an N-channel field-effect device, so although the index category is schematic, the content is…

Listed as a schematic, this 125 KB PDF is named after the 2SK1466, a part code that under the Japanese JIS scheme denotes an N-channel field-effect transistor.

Short 37.3 KB PDF for the 2SK544, a part number belonging to the JIS 2SK series of N-channel FETs; although indexed as a schematic, it should be a component datasheet.

Catalogued among schematics, the 43.5 KB PDF called 2SJ499's neighbour 2SJ485 refers to a semiconductor part; under the JIS scheme the 2SJ prefix designates a P-channel…

A 92.5 KB PDF named after 2SJ256, a JIS-numbered P-channel field-effect transistor according to its 2SJ prefix.

Catalogued as a schematic, this 88.5 KB PDF is named only 2SJ230, a JIS code in which the 2SJ prefix identifies a P-channel field-effect transistor.

PDF datasheet of about 56 KB for the 2SD661 transistor, with an _E suffix that probably indicates an English edition.

Here is a 42.3 KB PDF for the 2SC5264LS, indexed as a schematic. JIS numbering makes the 2SC prefix an NPN bipolar transistor, and the LS letters identify a variant of…
