PDF document for the IRFP260 power MOSFET, catalogued under schematics although the name points to a component datasheet.

Datasheet in PDF form for the IRFP250 N-channel power MOSFET, a compact 92.6 KB file. Expect absolute maximum ratings, on-resistance, gate charge, safe operating area…

IRF640 MOSFET datasheet in PDF format, about 112 KB in size. It should provide electrical ratings, on-resistance, gate threshold, thermal resistance and package drawings…

Datasheet for the 2SK2043 N-channel MOSFET, with the file name stating a 600 V drain-source rating and 2 A drain current.

PDF of 43.6 KB for the 3N252, listed under schematics though the name is a bare JEDEC part number.

A 111 KB PDF for the 2SD2281, which under the Japanese JIS system is an NPN transistor from the low-frequency 2SD series.

Small 45.6 KB PDF named 2SD1902, a Japanese standard transistor number; despite the schematic label it is most probably a short datasheet.

PDF documentation, 431 KB, for the 2SK2883 N-channel FET, placed in the schematic section of the catalogue.

Part reference for the 2SK2862 in a 411 KB PDF, listed under schematics in this index. The name carries only the transistor number.

Datasheet-type PDF for the 2SK2740, 138 KB, with a 1-5 suffix in the name whose meaning is not stated, possibly an edition or page range.

PDF of 137 KB for the 2SK2713, carrying a 1-5 suffix of unstated meaning, likely an edition or page marker rather than a different device.

Part-number-only PDF for the 2SK2323, 23.2 KB, placed in the schematic category of the index.

Datasheet-style PDF of 142 KB for the 2SK2299N, listed as a schematic. In JIS nomenclature 2SK identifies N-channel field-effect transistors, and the trailing N is part…

PDF of 33.4 KB describing the 2SK2016 transistor, an N-channel FET by its JIS 2SK prefix. It is catalogued as a schematic but is best used as a component datasheet.

Datasheet-style PDF for the 2SK1840, sized 87.3 KB. Part numbers beginning with 2SK are registered under the Japanese JIS scheme for N-channel field-effect transistors.

A 291 KB PDF dedicated to the 2SK1830. The 2SK code is the Japanese JIS designation for N-channel field-effect transistors, so this is almost certainly a datasheet…

An 88.5 KB PDF on the 2SK1738 transistor. In the JIS system, 2SK designates an N-channel FET, so this file is most likely the datasheet rather than a circuit schematic.

The 2SK1489 named here is a discrete transistor code: under JIS numbering, 2SK denotes an N-channel field-effect transistor.

Reference PDF for the 2SK1457, filed under schematics and 122 KB in size. The file name carries only the part number.
