The 2SD2179 transistor is the subject of this 43.9 KB PDF, carrying an _E suffix in its name.

The 42.4 KB PDF is named for the 2SD2345 and carries an _E suffix, whose meaning the name does not explain.

A small 40.3 KB PDF for the 2SK2867, filed as a schematic; the modest size suggests a short datasheet or summary page. The name contains nothing but the part number.

A 98.4 KB PDF titled with the part number 2SC4162, filed under schematics but in practice expected to be the datasheet for that transistor.

Datasheet-style PDF for the 2SC5646 transistor, 31.7 KB, placed in the schematic category.

Datasheet-style document for the 2SC5405, stored as a 37.3 KB PDF in the schematic category. Nothing beyond the part number appears in the name.

The 2SC3153 is the subject of this 98.0 KB PDF, catalogued as a schematic though the name points to a discrete-part data sheet.

Small 40.7 KB PDF named 2SC2925 with an added _E suffix, classified here as a schematic.

Part number 2SC2851 with an _E suffix names this 48.7 KB PDF, listed as a schematic. The 2SC prefix follows JIS numbering for NPN bipolar transistors, so a datasheet is…

Reference sheet for the 2SA1244 transistor in PDF form, 295 KB, listed as a schematic even though the name gives nothing beyond the part number and the file is most…

Datasheet PDF of 229 KB for the 2SA1162, a PNP bipolar transistor named under the Japanese JIS 2SA convention.

Component sheet for the 2SA1723, an 80.1 KB PDF. The name holds only the part number, so no equipment model or board revision can be attached to it.

Part reference for the 2SA1708, saved as a 154 KB PDF. No device, brand or board number is present in the name, only the component designation.

A PDF of about 155 KB for the JEDEC part number 2N6338, filed under schematics but almost certainly a component datasheet.

Preamplifier schematic, the file name being the Romanian word for preamp, delivered as a 574 KB PDF with no model or brand stated.

PDF covering the BF458 and BF459 transistors, a compact 49.2 KB file listed as a schematic but most likely a shared datasheet.

Data sheet for the BC237 NPN small-signal transistor, supplied as a 54.8 KB PDF. It should include package outline, terminal arrangement, maximum ratings, gain groups…

The 2SD2285 is documented in this 128 KB PDF. Its JIS part number, with the 2SD prefix, places it among NPN transistors intended for low-frequency circuits such as…

The 2SD1907 is covered by this 165 KB PDF, which is catalogued as a schematic but by name is a component datasheet.

The 2SK545 is covered by this 80.4 KB PDF, filed as a schematic but most likely a datasheet because 2SK numbers identify N-channel field-effect transistors in the…

An 88.2 KB PDF carrying only the part number 2SC4125, filed as a schematic though it is most likely a component datasheet.
