PDF reference on the 2SC4517 transistor, the name noting it as NPN; the file is 26.9 KB and indexed as a schematic.

Datasheet in PDF format for the 2SC4161, 130 KB in size. The 2SC prefix in Japanese JIS numbering identifies an NPN bipolar transistor, and the sheet should give voltage…

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

Combined datasheet for the BC546 and BC547 NPN small-signal transistors, packaged as a 57.5 KB PDF.

Catalogued as a schematic, this 27.2 KB PDF carries only the code 3LP01SS, which looks like a component part number with a two-letter SS suffix.

Named 3LN02C, this 41.8 KB PDF is filed among schematics but its name is a component-type code with a C suffix and gives no device or board details.

Another copy of documentation for the 2SD1458 NPN transistor, stored as a 48.8 KB PDF under a lowercase file name.

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.

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.

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

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…

Samsung SM-A205F schematics, the Galaxy A20, provided as PDF files inside a RAR archive of about 4.06 MB.

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.

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 only 2SC4161, this 98.6 KB PDF is categorised as a schematic yet, judging by the part number, documents an NPN bipolar transistor under the JIS designation scheme.

Stored under schematics, this 93.8 KB PDF is named for the 2SC4123 and is expected to hold the transistor's datasheet rather than a circuit drawing.

The largest of this group at 334 KB, this PDF is named only 2SC4117 and, while labelled a schematic, should be the datasheet for that NPN bipolar transistor under…
