Datasheet-style document for the 2SD2581 transistor, saved as a 43.7 KB PDF and filed in the schematic category.

Part datasheet for the 2SD1782K, an NPN transistor named under the Japanese JIS scheme, with the K suffix indicating a particular variant or package.

The name offers nothing beyond the 2SD2500 part number, and the 250 KB PDF is almost certainly that transistor's datasheet.

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

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

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

Reference sheet for the 3SK180 semiconductor in PDF form, roughly 173 KB, catalogued as a schematic.

Filed under schematics, though the file name is simply the JIS part number 2SD1903, so expect a component datasheet in this 131 KB PDF.

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

The 2SK3291 transistor is the subject of this 34.2 KB PDF, filed as a schematic although it works as a datasheet.

Part reference for the 2SK2782, delivered as a 419 KB PDF under the schematic label. The 2SK prefix follows Japanese JIS numbering for N-channel field-effect…

Reference PDF for the 2SK2714 transistor, 144 KB, filed in the schematic section. JIS naming uses 2SK for N-channel field-effect transistors, so the contents should be a…

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…

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

Filed under schematics, this 138 KB PDF is named after the 2SK2463, a JIS-style part number, so it is most likely a component datasheet rather than a board drawing.

Document for the 2SK2400, 403 KB in PDF format and listed as a schematic, although the name points to a single-component datasheet.

The 2SK2312 is covered by this 391 KB PDF, catalogued under schematics yet most likely a component datasheet.

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

Component documentation in a 114 KB PDF for the 2SK2011. Parts with the 2SK prefix are N-channel field-effect transistors under the Japanese numbering standard, so this…

The 2SK1826 datasheet in PDF form, sized 320 KB and filed as a schematic. Japanese JIS designations starting with 2SK identify N-channel field-effect transistors.

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…

At 120 KB, this PDF is a slightly larger reference for the 2SK1728. Japanese JIS/JEITA numbering assigns the 2SK series to N-channel field-effect transistors, so expect…

Catalogued under schematics, this 112 KB PDF is tied to the 2SK1450 and is most likely a component data sheet.

Reference PDF for the 2SK1382 N-channel MOSFET, 389 KB, listed in the schematic category of the index.

Datasheet PDF for the 2SK1058, a 55 KB file. This part number belongs to the 2SK series of N-channel field-effect transistors and is widely known from audio power…

Reference sheet for the 2SK937 transistor, a 79.9 KB PDF. Parts in the 2SK range are N-channel field-effect transistors under the Japanese JIS designation.

Covering the 2SJ612, this 29.0 KB PDF sits in the schematic category, though a bare part number usually denotes a datasheet.

Datasheet-style PDF of 31.0 KB for the 2SJ595, catalogued among schematics. JIS designations starting with 2SJ belong to P-channel field-effect transistors.

Covering the 2SJ589LS, this 33.2 KB PDF is catalogued as a schematic, though the name points to a component datasheet.

Part documentation for the 2SJ337 in a 98.2 KB PDF. The file name names only this semiconductor, nothing about a device.

Catalogued among schematics, this 103 KB PDF is labelled only 2SJ263. In the Japanese JIS designation system the 2SJ prefix covers P-channel field-effect transistors, so…

Datasheet for the 2SD662 NPN transistor, stored as a 44 KB PDF; the _E ending likely marks an English version of the document.

A 155 KB PDF bearing the part number 2SC4734 and nothing else. The 2SC prefix belongs to the JIS/JEITA system for NPN bipolar transistors, so despite the schematic label…

Here is a 144 KB PDF for the 2SC4728, filed as a schematic but carrying a discrete part number.

Small 37.9 KB PDF for the 2SC4715, with an _E suffix in the name whose meaning is not stated, possibly a language or document edition marker.

PDF of about 63 KB for part 2SC4618, with a trailing h in the name whose meaning is not stated and may denote a variant or document version.

Small 39.3 KB PDF covering the 2SC4562, with an unexplained _E suffix in the name, listed under schematics.

PDF reference for transistor part 2SC4428, 107 KB, indexed under the schematic category.

PDF of 60.0 KB named 2SC5127, categorized as a schematic though it should be the device datasheet for that NPN bipolar transistor.

Part datasheet for the 2SC5589 in PDF, 298 KB, grouped with schematics in this index. The file name states only the part number.
