Part reference for the 2SD1669, supplied as a 107 KB PDF and filed in the schematic section.

Transistor documentation for the 2SD1667, 136 KB in PDF format. Nothing beyond the part number appears in the name.

At 198 KB, the PDF for the 2SD1658 is one of the larger sheets in this group, though it still names only the part.

The 3N248 is covered by this 43.6 KB PDF, indexed under schematics but named only by its JEDEC part number.

Part number 2SD2459 names this 41.2 KB PDF, followed by an unexplained E tag; it is catalogued as a schematic.

Short 54.7 KB PDF for the 2SD1991A, an NPN bipolar transistor going by its JIS 2SD prefix. The index lists it under schematics.

The name carries only a part number, 2SD1905, which points to a semiconductor datasheet even though the entry is filed under schematics.

Datasheet-type PDF of 31.1 KB for the 2SK3412 semiconductor, stored under the schematic category.

Covering the 2SK3335, this small PDF (32.6 KB) is a part datasheet placed in the schematic category.

PDF reference for the 2SK2825, 301 KB in size and listed in the schematic section. The 2SK designation, from the Japanese JIS numbering system, belongs to N-channel…

Reference PDF for the 2SK2711, about 140 KB, listed in the schematic category though the part number points to a discrete transistor datasheet.

Brief 34.7 KB PDF for the 2sk2581 transistor, catalogued as a schematic. JIS naming assigns 2SK to N-channel field-effect transistors, and the name gives no further…

Reference sheet in PDF format for the 2SK2549 field-effect transistor, 373 KB in size. In the JIS numbering used by Japanese semiconductor makers, 2SK denotes an…

PDF documentation for the 2SK2544 N-channel FET, following the Japanese JIS 2SK naming pattern, with a file size of 409 KB.

Brief PDF, about 30.2 KB, for the 2SK2509, a JIS-designated N-channel FET as indicated by its 2SK prefix.

The 2SK2504 transistor is documented in this 134 KB PDF, named in lowercase and catalogued under schematics.

Small 33.8 KB PDF on the 2sk2495, a part number in the JIS N-channel FET series marked by the 2SK prefix.

For the 2SK2313 transistor, this 419 KB PDF is filed as a schematic but is expected to be a datasheet, since 2SK is the JIS prefix for N-channel FETs.

A 396 KB PDF for the 2SK2274, listed under schematics but most likely a datasheet, since 2SK denotes an N-channel FET in the JIS numbering scheme.

A 398 KB PDF for the 2SK2034, a part in the Japanese 2SK series of N-channel field-effect transistors.

Compact 31.6 KB PDF dedicated to the 2SK2032. Because 2SK identifies an N-channel field-effect transistor in the Japanese numbering scheme, this is effectively a…

PDF reference, 115 KB, for the 2SK1924 N-channel field-effect transistor; the 2SK prefix places it in the Japanese JIS transistor registry.

PDF for the 2SK1739A, 197 KB, listed as a schematic. The 2SK prefix follows the Japanese JIS designation for N-channel field-effect transistors, and the trailing A…

Short 31.7 KB PDF for the 2SK1460LS, an N-channel FET by the Japanese 2SK prefix, carrying an LS suffix that distinguishes it from the plain 2SK1460 also in this index.

The 2SK1120 N-channel field-effect transistor is documented in this 455 KB PDF, one of the larger sheets in the set and probably including full characteristic curves and…

Component datasheet for the 2SK1057, packaged as a 55 KB PDF. The 2SK prefix marks an N-channel FET in the Japanese numbering system, and this number sits in the same…

Datasheet-type PDF for the 2SK536, 60.8 KB, catalogued under schematics. Under the Japanese JIS system the 2SK designation means an N-channel FET, so the content…
