Small 41.8 KB PDF for the 2SB792, filed as a schematic but named only after a part number, so it is most likely the component datasheet.

UTC version of the 2SB772 documentation, a 22.5 KB PDF; UTC very likely stands for Unisonic Technologies.

Datasheet-style PDF for the 2SA1339, indexed in the schematic category at 140 KB. The 2SA prefix denotes a PNP transistor in the JIS scheme, nominally aimed at…

A 195 KB PDF labelled 2SA2060, a part number in the Japanese JIS system where 2SA denotes a PNP bipolar transistor.

PDF document for the 2SA1318, filed in the index as a schematic but named after a single semiconductor part number, so it most likely holds the component datasheet.

Component documentation for the 2SA1314 in PDF format, 162 KB. The type field says schematic, but the name consists only of the part code, which normally means a…

A 40.8 KB PDF for the 2SA1290 transistor, catalogued under schematics. The filename states only the part number; the 2SA prefix designates a PNP bipolar device in the…

A 43.6 KB PDF on the 2SA1209, filed under schematics but named solely by the part code, so most likely a short datasheet.

Datasheet covering the 2SA1806, stored as a 44.6 KB PDF whose name carries an E suffix, probably indicating an edition or language version of the document.

A compact 50 KB PDF named after the JEDEC-registered part 2N720A, indexed under schematics but almost certainly a component datasheet rather than a board drawing.

This 26.1 KB PDF, placed in the schematic section, is named after the 2N6517, part of the JEDEC 2N numbering used for discrete transistors and similar devices.

PDF datasheet for the 2N5457 N-channel JFET, 111 KB, filed under schematics. The RE suffix in the name is not explained and may mark a reissued or alternate vendor copy…

Reference sheet for the 2N5457, a general-purpose N-channel junction field-effect transistor, saved as a 130 KB PDF.

PDF reference sheet for the 2N5320 transistor, 45.0 KB, sitting alongside the 2N5322 document in the index. No vendor or revision is named.

A 45.3 KB PDF for the 2N3439, a JEDEC 2N-series transistor, indexed as a schematic but actually a part datasheet. No manufacturer or revision appears in the name.

A 71.2 KB PDF with data for the 2N2222, filed with schematics in this index. The 2N2222 is a staple NPN small-signal transistor used for switching relays, LEDs and logic…

Catalogued as a schematic, this 56.9 KB PDF is labelled 1SV237. The trailing underscore in the name appears to be a naming artefact, not part of the code.

Catalogued as a schematic, this 74.6 KB PDF is named after the 1SV269 part number, with a trailing underscore that carries no extra information.

PDF reference for the 1SS404 part, filed under schematics, though the 1SS numbering points to a Japanese small-signal diode and the file is probably its datasheet.

Listed among schematics, this 78.7 KB PDF covers the 1SS399, a number that follows the Japanese 1SS small-signal diode designation.

A 68.3 KB PDF labelled with only 1SS306 and catalogued as a schematic, with no brand or board mentioned.

PDF datasheet covering the 1N4148 and 1N4448 fast switching diodes, filed in the schematic section of the index.

Filed under schematics, this 93.2 KB PDF carries only the part code 1N3208, a JEDEC style 1N designation normally given to diodes, so expect a manufacturer datasheet…

Only the part code 245NQ015 appears in the name of this 94.4 KB PDF, suggesting a datasheet for a high current rectifier device rather than a circuit diagram.

Catalogued as a schematic, but the part number 224CNQ035 follows International Rectifier style Schottky rectifier naming, so the PDF is most likely a component datasheet…

Named 110rki40, this small 63.9 KB PDF is filed under schematics yet the title looks like a power semiconductor part designation, not a device or board.

Spanning 1SMA10CAT3 to 78CAT3 according to its name, this 81.5 KB PDF is filed as a schematic but describes a component range, the CA suffix typically marking…

Named 100bgq045, this 85.8 KB PDF is filed among schematics, though the title reads as a power rectifier part code rather than a board number, and no device, brand or…

Catalogued as a schematic, this 432 KB PDF named 29040l most likely documents a 4 Mbit 29-series parallel flash memory, the l suffix probably marking a low-voltage or…

A 111 KB PDF named 555 and grouped with schematics, with no brand or board stated. The number matches the widely used 555 timer designation, but the document should be…

PDF document of 203 KB filed as a schematic and named only 80CNQ035A. No device, motherboard number or revision is stated, and the code follows the pattern of a…

Listed under schematics, this 56.0 KB PDF carries only the short code 63cnq, without a full suffix, brand, model or board revision.

A schematic-category PDF of 129 KB whose name, 50WQ04FN, identifies no device, board number or revision.
