Larger 185 KB PDF for the 2SD2012, written in lowercase in the name and placed among schematics.

Very small 22.2 KB PDF relating to the 2SD1999, filed as a schematic. The name offers nothing but the part code, which follows the JIS scheme where 2SD denotes an NPN…

An 88.2 KB PDF titled 2SD1884, indexed in the schematic section but, judging by the bare part number, a datasheet for that transistor.

A 30.6 KB PDF for the 2SK3278, indexed as a schematic but holding component reference data.

Part datasheet, most likely, for the 2SK2837, provided as a 426 KB PDF and indexed as a schematic.

A 429 KB PDF titled 2SK2789 and stored among schematics, most likely the datasheet for that part.

Component datasheet for the 2SK2661, a 385 KB PDF that is indexed as a schematic. Under JIS naming, the 2SK prefix marks an N-channel field-effect transistor, so look…

Small 23.4 KB PDF for the 2SK2660 transistor. The 2SK designation comes from the Japanese JIS system for N-channel FETs, so the file is most likely a brief datasheet…

Part documentation for the 2SK2628LS, a 28.6 KB PDF. The 2SK prefix places it in the Japanese JIS family of N-channel field-effect transistors, and the LS suffix denotes…

PDF reference document of 413 KB for the 2SK2508 transistor, filed as a schematic. In JIS naming the 2SK prefix identifies an N-channel field-effect transistor; the name…

The 2SK2445 gives its name to this 410 KB PDF, categorised as a schematic yet most likely a datasheet, because 2SK codes in the JIS scheme identify N-channel FETs.

The part number 2sk2210 is the sole clue to this 33.6 KB PDF, catalogued under schematics but most likely a short component datasheet.

The 2SK2171 referenced in this 180 KB PDF is an N-channel field-effect transistor by JIS/EIAJ convention, which uses the 2SK prefix for that class.

The 2SK2129, a JIS-registered N-channel FET, is the only thing the name identifies in this 32 KB PDF.

PDF of 98.9 KB for the 2SK1898, listed under schematics but in practice a component reference for one transistor.

Only the part number 2SK1897 identifies this 97.1 KB PDF, which the index places among schematics.

PDF reference, 105 KB, for the 2SK1813 transistor. In the Japanese JIS scheme, 2SK designates an N-channel field-effect transistor, so this is probably its datasheet.

A 105 KB PDF for component 2SK1432, categorised as a schematic though the name identifies only a single transistor.

For the 2SK1427 N-channel FET, this 101 KB PDF sits in the schematic section of the index but most likely contains a datasheet.

PDF sheet for the 2SK1233 MOSFET, size 46.1 KB, part of the Japanese 2SK series of N-channel field-effect transistors.

Short 34.3 KB PDF for the 2SK1228 N-channel field-effect transistor, catalogued among schematics. The 2SK prefix identifies a JIS-registered Japanese N-channel FET.

Reference document for the 2SK1062, provided as a 334 KB PDF. The 2SK designation identifies an N-channel field-effect transistor in the Japanese numbering scheme, and a…

The 2SK657 datasheet, filed as a schematic, is a 35.7 KB PDF; the 2SK prefix identifies an N-channel FET in the Japanese semiconductor numbering scheme.

Indexed as a schematic, this 33.9 KB PDF for the 2SK655 is best read as a transistor datasheet, since 2SK numbers designate N-channel FETs under the Japanese JIS…

Datasheet PDF, roughly 82.3 KB, for the 2SK222, catalogued among schematics. The JIS 2SK series denotes N-channel field-effect transistors, and the name supplies no…

Small PDF document, 28.8 KB, identified only by the part number 2SJ615 and filed as a schematic.

PDF of 42.8 KB for part 2SJ585LS, listed under schematics. JIS semiconductor coding assigns 2SJ to P-channel FETs, so this is most probably a datasheet with ratings…

The 2SJ584LS is documented in this 42.9 KB PDF, placed in the schematic category but named as a single-part datasheet.

PDF reference of 42.4 KB for the 2SJ578 part, listed in the schematic section. Japanese JIS coding gives the 2SJ prefix to P-channel field-effect transistors, so the…
