Compact 125 KB PDF for the 2SC5091FT, an NPN bipolar transistor numbered under the Japanese 2SC scheme, with the FT suffix as part of the name; its exact meaning is not…

Part reference for the 2SC4987, provided as a 110 KB PDF and filed under schematics. No model, board or revision is stated in the name.

A 135 KB PDF identified only by the part number 2SC3787. While the index files it as a schematic, the JIS designation 2SC indicates an NPN bipolar transistor, which…

Component document for the 2SC4809 transistor, filed under schematics but by its name and small size most likely a manufacturer datasheet.

A larger 225 KB PDF for the 2SC3710A, an NPN transistor under the Japanese JIS designation, indexed as a schematic.

PDF reference for the 2SC3596, sized at 119 KB and indexed with schematics although it describes a single semiconductor.

Named for the 2SC2995, this 510 KB PDF is listed as a schematic but most likely holds the datasheet for a JIS-numbered NPN transistor, as the 2SC prefix indicates.

Named after the JIS part number 2SC2816, this 50 KB PDF appears in the schematic category but most likely contains the datasheet of an NPN bipolar transistor, as the 2SC…

The 2SB1589 PNP transistor is described in this 40.1 KB PDF datasheet, with an _E suffix that most likely points to the English edition.

Reference sheet in PDF form for the 2SA1593 transistor, 156 KB in size. The name gives only the part number, with no device or board details.

Datasheet PDF covering the 2SA1588, 215 KB in size, which suggests several pages with curves and package details.

The 2SA1572 transistor is documented in this 49.4 KB PDF. No board or equipment model appears in the name, so treat it as a component datasheet.

Short PDF of 47.9 KB named 2PC945 with suffix 3, which likely marks the data sheet revision.

PDF document of 238 KB covering the 2N4398 device, with an RE suffix in the name whose meaning is not stated, possibly a reissued or revised sheet.

Filed as a schematic, 1SV231 is a 68.1 KB PDF named after a component code; the trailing underscore is not part of it.

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.
