PDF sheet for the 1SV160, catalogued as a schematic. The name adds V1, probably a document version, and sot323, the small three-lead SOT-323 surface-mount package.

PDF for the 1SV316, catalogued under schematics, with UV and sot323 added to the name. SOT-323 is a small three-lead surface-mount package, while the UV token is not…

Part documentation for the 1SS400, an 86.6 KB PDF classed as a schematic. The 1SS designation belongs to the Japanese family of small-signal silicon diodes, so expect a…

A 67.7 KB PDF reference for the 1SS395, recorded as a schematic in the index. The 1SS prefix is the Japanese JIS-style designation for small-signal diodes, so the…

Catalogued as a schematic, this 69.5 KB PDF is named after the part number 1SS381, so it is most likely a component data sheet.

A compact PDF of 53.8 KB indexed as a schematic, named only after the part number 1SS350.

Larger than most of its neighbours at 123 KB, this PDF is named only 1SS313 and gives no device or board details.

Catalogued as a schematic, this 129 KB PDF is named after the part number 1SS271, which reads like a component datasheet rather than a board drawing.

Very small at 10.8 KB, this PDF named 1n6778 looks like a brief datasheet or spec page for a JEDEC 1N-numbered semiconductor, despite being indexed as a schematic.

PDF datasheet of 246 KB for the 1N4937 diode, with a plus sign in the name that is probably just a file label rather than a part suffix.

Datasheet for the 1N4454 diode, a very small 19.5 KB PDF that probably holds a short single-page summary.

Catalogued as a schematic, this 72.5 KB PDF carries only the code 80CNT020A, with no board, brand or revision given.

The file 70mtkb is a 73.3 KB PDF filed as a schematic, and its name provides no brand, model or PCB revision.

Filed under schematics, this 199 KB PDF carries the name 32CTQ030, which reads like a discrete semiconductor part number in the style of Schottky rectifier designations…

Named 16TTS-S, this 109 KB PDF is catalogued as a schematic, but the name looks like a discrete semiconductor code with a suffix, not a board identifier.

Marking-code guide in PDF for Micro Commercial Components (MCC), a maker of diodes, transistors, MOSFETs and other discrete semiconductors.

Part datasheet in PDF for the MJE13007F, a high-voltage NPN switching transistor. The F suffix usually denotes an isolated fully plastic package, though the name states…

PDF titled only with the part number D304X, about 489 KB, filed as a schematic. The name gives no further detail on device type or manufacturer, so the contents are most…

Component reference for the 5LP02C, a 42.3 KB PDF that the index lists as a schematic. The name carries just the part code, where the LP letters appear to mark a…

Reference PDF of 27.6 KB for the component 5HP01S, filed among schematics although it describes one discrete part.

PDF of 27.9 KB filed as a schematic under the code 3LN01S, which reads as a discrete component part number with an S suffix.

A 68.3 KB PDF bearing the name 2SD2324, a Japanese JIS designation for an NPN transistor, since 2SD marks NPN low-frequency devices.

Compact 23.1 KB PDF named only with the part number 2SK2277. Because 2SK is the JIS prefix for N-channel FETs, the schematic category here most likely holds a short…

The 2SK445 part number is all the name provides for this 89.6 KB PDF, filed as a schematic but best treated as a datasheet, as 2SK numbers designate N-channel…

The file name gives nothing beyond 2SJ562, a JIS-style designation; the 2SJ prefix denotes a P-channel field-effect transistor.

A 105 KB PDF for the 2SJ421, catalogued as a schematic but in practice a component datasheet, since the 2SJ prefix in the Japanese JIS numbering system marks a P-channel…
