Datasheet-style PDF for the BU2508DX, roughly 80 KB, indexed under schematics. This is a well known horizontal deflection transistor for CRT TVs and monitors, and the D…

Datasheet-style PDF covering the BD233, BD235 and BD237 family of medium-power transistors, filed here under schematics.

PDF data for the BC328 PNP transistor, the name listing minus 30 V and minus 800 mA ratings, filed under schematics at 53.5 KB.

The 3N258 is the subject of this 42.2 KB PDF, indexed as a schematic but in practice a component reference.

A fairly detailed 200 KB PDF for the 2SD2352, a JIS-numbered NPN transistor, where the 2SD prefix denotes NPN low-frequency parts.

Stored under a lowercase name, this 52.3 KB PDF covers the 2sd2318 transistor. In the Japanese JIS scheme the 2SD series contains NPN devices for low-frequency duty, so…

PDF reference of 221 KB for the 2SK2909, catalogued as a schematic. Only the part number is present in the name, with no maker or revision indicated.

Component sheet for the 2SK2886 transistor, delivered as a 424 KB PDF and filed in the schematic category. The name carries only the part number.

PDF document for the 2SK2775, filed under schematics although the part number points to a component datasheet rather than a board drawing.

A compact 23.3 KB PDF for the 2SK2772, an N-channel FET according to the JIS 2SK naming convention, catalogued here as a schematic.

The 2SK2750 is covered by this 394 KB PDF, indexed as a schematic but most likely the component datasheet, since 2SK is the JIS prefix for N-channel FETs.

A 135 KB PDF covering the 2SK2711 transistor. The extra 1-5 token in the name is not explained and may point to a page range or document revision.

Component document for the 2SK2611, a part number in the Japanese JIS scheme where the 2SK prefix marks an N-channel field-effect transistor.

The smallest sheet of its group at 24.4 KB, this PDF concerns the 2sk2573, an N-channel field-effect transistor by the JIS 2SK prefix.

Reference PDF for the 2SK2459N, sized 133 KB and indexed as a schematic, though the JIS-style name points to a single-component datasheet for an N-channel FET.

Compact 33.0 KB PDF on the 2SK1834 transistor. The 2SK prefix belongs to the Japanese JIS designation system and means an N-channel field-effect device, so the content…

The name 2SK1446LS marks this 32 KB PDF as covering an LS-suffixed version of the 2SK1446.

Datasheet-style PDF for the 2SK1412LS, a Japanese 2SK-series N-channel field-effect transistor, filed in the index under schematics.

Datasheet-style PDF for the 2SK669, a part number in the JIS 2SK series used for N-channel field-effect transistors, listed in the index as a schematic.

Reference PDF for the 2SK620, a JIS-series N-channel field-effect transistor, weighing 35.6 KB and listed under schematics though it is most likely a datasheet.

Only the part number 2SJ512 appears in the name of this 455 KB PDF, which the index lists among schematics.

At just 31.4 KB, the PDF named 2SJ499 is probably a short datasheet or summary sheet, even though it is filed as a schematic.

The 2SJ419 is covered by this 100 KB PDF, filed under schematics though the part number points to a discrete transistor datasheet.

Catalogued as a schematic, this 93.1 KB PDF is named only after the part number 2SJ281, which follows the Japanese JIS scheme where the 2SJ prefix denotes a P-channel…

At 294 KB, this PDF is larger than its neighbours but still identified only by 2SJ167, a Japanese JIS number for a P-channel field-effect transistor.

Indexed as a schematic, the 44.5 KB PDF named 2SD1328_E should be a datasheet for the 2SD1328, which the JIS 2SD prefix identifies as an NPN bipolar transistor for…

PDF document of 41.7 KB for the 2SC4737, filed in the schematic category but named after a part rather than a board.

Filed under schematics, this 98 KB PDF is named after the part number 2SC4671, which follows the Japanese JIS designation for an NPN bipolar transistor.

Datasheet in PDF form for the 2SC4696, filed in the index under schematics although the name points to a discrete part document rather than a board diagram.

The 2SC4163 part number is all this 98.9 KB PDF name reveals, so although labelled a schematic it is best read as a transistor datasheet.

Named in lowercase for the 2sc4132, this 63.0 KB PDF is classed as a schematic but is better understood as the datasheet for an NPN bipolar transistor, which is what the…
