The 2SK2792 part number appears here with an unexplained 1-5 suffix, possibly a page range or edition marker.

A PDF of about 88 KB for the 2SK2154, filed under schematics but most likely a component datasheet, since the name is just the part number.

A PDF filed under schematics but named after the 2SK404, a part number in the Japanese JIS semiconductor scheme, where the 2SK prefix marks an N-channel field-effect…

A 39.6 KB PDF for the 2SC5216, with an _E tag in the name that is not explained. It is listed as a schematic, but the name points to a transistor datasheet.

Catalogued as a schematic, this 184 KB PDF is named only after the part number 2SC5175, so it is most likely the manufacturer datasheet for that discrete transistor.

For the 2SC5534 transistor, this 44.8 KB PDF sits in the schematic category but, going by the JIS 2SC code for NPN bipolar devices, is the part datasheet.

Here is a 49.4 KB PDF for part 2SC4067, placed under schematics but named like a manufacturer datasheet.

Catalogued as a schematic, this 100 KB PDF is named after the 2SC4031 and is most likely its datasheet. JIS numbering uses 2SC for NPN bipolar transistors.

PDF documentation for the 2SC3929 transistor, 54.1 KB, suffixed _E and filed under schematics.

A small PDF filed as a schematic, though the name is simply the part number 2SC3468, which follows the Japanese JIS semiconductor scheme where the 2SC prefix marks an…

Catalogued as a schematic, this 190 KB PDF is named after the 2SC2999, a part number in the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar transistor.

A 186 KB PDF identified by the part number 2SC2873 and classed as a schematic. Under the JIS standard the 2SC prefix means an NPN bipolar transistor, so this is most…

Data document for the 2sb1590k, a 34.8 KB PDF listed under schematics. The 2SB part follows JIS numbering for PNP low-frequency bipolar transistors; the trailing K is a…

Reference PDF, 88.0 KB, for the 2SA1582 transistor. The file name states only the part number and nothing about the maker, package or application.

Named after the 2SA1537 transistor, this 41.0 KB PDF sits in the schematic category but should contain the manufacturer data for that part.

This 52.0 KB PDF covers the 2SB1218A, the A suffix being part of the stated part number, with a further _E tag in the name; despite the schematic category it is likely a…

Small 21.4 KB PDF for the 2SA733 PNP transistor, with the UTC tag in the name pointing to the Unisonic Technologies version of this widely used general-purpose part.

Specification document for the 2SA1728, provided as a 91.2 KB PDF with no board or device model in its name.

Part number 2N5770 is the only detail this 296 KB PDF carries. It is listed as a schematic but names no board or laptop model.

Very small PDF of 26.3 KB named with the part number 2N5639 and nothing else. Listed as a schematic, it is most plausibly a short datasheet, since 2N codes are JEDEC…

A 755 KB PDF bearing only the part code 2N5484 and grouped with schematics. Matching sizes with the 2N5485 and 2N5486 files hint at a common datasheet for the whole…

Component datasheet for the 2N5366, a 60.8 KB PDF filed in the schematic category. The name gives only the part number, with no manufacturer, package or revision…

A 57.0 KB PDF listed as a schematic and named 1SV216, followed by an underscore that appears to be a naming leftover.

Part 1SS370 is the sole identifier in this 66.2 KB PDF name, which suggests a data sheet for a single small-signal silicon diode, the meaning of the 1SS prefix in JIS…

Series datasheet for the 1N5221 to 1N5281 zener range, a compact 35.5 KB PDF filed as a schematic.
