Datasheet-style PDF, 55.1 KB, for the 2SK2347 semiconductor, stored in the schematic section of the index.

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.

A 396 KB PDF for the 2SK2274, listed under schematics but most likely a datasheet, since 2SK denotes an N-channel FET in the JIS numbering scheme.

The file name gives nothing beyond 2SK2233, a JIS/EIAJ designation whose 2SK prefix marks an N-channel field-effect transistor.

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

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

Compact 33.4 KB PDF for the 2SK1374, a Japanese-numbered N-channel MOSFET. Only the part number appears in the file name, so the issuing manufacturer and exact package…

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

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.

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.

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…

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

Reference sheet for the 2SD1062 transistor in PDF form, about 104 KB, catalogued under schematics.

PDF of 208 KB covering the 2SC5550, listed in the index under schematics but by its JIS part code an NPN bipolar transistor, so treat it as a component datasheet.

Covering the 2SC3150 transistor, this 103 KB PDF sits in the schematic category of the index.

Reference PDF covering the 2SB1530 transistor, filed under schematics but in practice a component datasheet identified only by its JIS part code.

PDF of 90.6 KB for the 2SB1131, listed in the schematic category though the name is simply a component number.

PDF reference for the 2SA1437, 77.6 KB, sorted into the schematic section. In the JIS system the 2SA prefix marks PNP transistors suited to high-frequency circuits.

A 214 KB PDF for the 2SA1429 part, catalogued as a schematic though most likely a data sheet.

Datasheet in PDF form for the 2N5322 bipolar transistor, about 44.9 KB. Nothing beyond the part number appears in the name, so the manufacturer and revision are unknown.

PDF datasheet of 34.8 KB for the 1N4446, a small signal switching diode belonging to the same general group as the 1N4148 and 1N4448.

The name 151cmq carries no board or equipment model, only a component code, so this 44.3 KB PDF is likely a datasheet for a common-cathode Schottky rectifier family…

A larger 678 KB PDF for the 40MT120UH, filed as a schematic. In this naming family the MT prefix points to a power module, and parts with this kind of suffix are…

English PDF titled basic electronics, 583 KB, not tied to any device or board. It is reference and training material rather than a service schematic.
