The name of this 421 KB PDF carries just one token, 2SK2836, a JIS-format number for an N-channel FET.

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…

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.

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.

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

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 datasheet of 287 KB for the 2SK2009, an N-channel field-effect transistor under the Japanese 2SK designation.

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

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 documentation for the 2SK1731 discrete semiconductor, roughly 90 KB in size. Japanese 2SK numbering identifies it as an N-channel FET; the name says nothing about…

For the 2SK1470, a Japanese-coded N-channel field-effect transistor, this 97.9 KB PDF serves as component reference material even though it sits in the schematic…

The 2SK1468 transistor is covered by this 92.5 KB PDF, categorised as a schematic though the name is purely a part number.

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.

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…

PDF covering the 2SK1104, an N-channel FET identified by the 2SK prefix of the Japanese semiconductor numbering system.

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

Brief 24.7 KB PDF for the 2SJ0398, written with a leading zero in the name, which most likely refers to the 2SJ398 P-channel FET in JIS numbering.

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…

This 93.0 KB PDF carries the part number 2SJ258 and nothing else. The 2SJ prefix, under Japanese JIS numbering, indicates a P-channel field-effect transistor, so expect…

The name of this 92.4 KB PDF consists only of 2SJ255, a Japanese JIS designation where 2SJ marks P-channel FETs.

Named only 2SJ232, this 88.9 KB PDF relates to a P-channel field-effect transistor, as indicated by the JIS 2SJ prefix.

Here is the 2SC5242 documentation as a 173 KB PDF, placed in the schematic category but evidently a part datasheet going by its name.

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

Reference PDF for the 2SC4224, at 97.3 KB, catalogued as a schematic although the name is just a semiconductor part number.

Compact 39.7 KB PDF named 2sc4849, written in lowercase but following the Japanese JIS pattern where 2SC denotes an NPN transistor.

The 2SC4909 NPN transistor is documented in this 61 KB PDF, listed under schematics but by its name a component datasheet.

Part number 2SC5354 is all the name reveals about this 129 KB PDF, so it is not tied to any identified device.

PDF reference sheet for the 2sb1236 transistor, 52.0 KB. The file name carries the part number only, with no further detail.

PDF component reference, 101 KB, describing the 2SA1798 transistor, listed in the schematic section of the index.
