The 2SC5171 named in this 169 KB PDF is a JIS-style part number, where the 2SC prefix denotes an NPN bipolar transistor for high-frequency applications, so the content…

The 2SC5144 is the only detail this 206 KB PDF name carries; despite the schematic label it is presumably the device datasheet for that transistor.

Compact 43.3 KB PDF covering the 2SC5551, a JIS-coded NPN bipolar transistor, even though the catalogue type says schematic.

A 39.3 KB PDF for the 2SC5490 component, which belongs to the 2SC range of NPN bipolar transistors under Japanese JIS numbering.

Component reference for the 2SC3124, a 294 KB PDF indexed as a schematic. The JIS 2SC designation identifies it as an NPN bipolar transistor, normally marked C3124.

The 2SC3116 NPN transistor is described in this 47.6 KB PDF, placed in the schematic category.

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.

Named 2SC2859, this 192 KB PDF is indexed among schematics but probably holds the datasheet of a JIS-numbered NPN bipolar transistor, as the 2SC prefix suggests.

A 190 KB PDF holding the data document for the 2SB1640 transistor, indexed under schematics.

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.

Small 44.1 KB PDF named after the 2SA1292, a PNP bipolar transistor according to the JIS 2SA designation.

Specifications for the 2SA1873 PNP transistor, provided as a 247 KB PDF. The 2SA prefix comes from the JIS semiconductor naming system and denotes a PNP bipolar part, so…

A 179 KB PDF for the 2SA1160, a PNP transistor from the JIS 2SA series. The name carries only the part number, so treat the document as the component datasheet rather…

A compact 43.5 KB PDF filed under schematics and named for the 2N6547, a part number from the JEDEC 2N registration series for discrete semiconductors.

Indexed under schematics, this 26.9 KB PDF is labelled 2N6518, a JEDEC-registered discrete semiconductor designation.

At 329 KB this is the largest sheet in the group, a PDF catalogued as a schematic for the 2N6515 with an unexplained RE suffix.

A 43.4 KB PDF listed among schematics and named for the 2N6515, a JEDEC 2N-series discrete semiconductor.

Reference PDF for the 2N5088, 282 KB, with an RE suffix in the name whose meaning is not stated and may mark a revised or alternate edition of the document.

PDF of 86.6 KB for the 2N4036, with an r0 tag in the name that likely marks a revision zero edition, though the file does not say so explicitly.

A compact 32.6 KB PDF for the 2N3773, a JEDEC-registered 2N-series transistor; despite the schematic label it is a component datasheet rather than a circuit drawing.

Data document for the 1SV302 diode, stored as a 72.1 KB PDF and catalogued as a schematic.

Single-component sheet for the 1SV291, saved as a 73.7 KB PDF and tagged as a schematic.

Varactor reference for the 1SV245, saved as a 73.9 KB PDF whose name ends in an underscore that adds nothing.

Specification sheet for the 1N5393 diode saved as a 42.7 KB PDF and indexed in the schematic category.

PDF datasheet for the 1N4152 switching diode, about 63.5 KB. The 1N4152 is a small signal fast switching diode in a glass axial package, used in the same kinds of…

For the 153cmq080, this 44.5 KB PDF is categorised as a schematic but almost certainly holds a datasheet for a common-cathode dual Schottky rectifier rated around 80 V.

Only the code 120lq100 identifies this 48.6 KB PDF, which is filed under schematics with no device, board or revision given.

Filed as a schematic, this 112 KB PDF covers the 1SR154 part with 400 and 600 variants named in the title, suggesting one sheet for two grades of the same component.

PDF document of 123 KB titled only 274001, an uninformative numeric name that does not identify the manufacturer or what is covered.

Indexed as a schematic, this PDF of 130 KB carries the code 50WQ10FN and nothing about a device or board.

Datasheet in a 106 KB PDF for the 27c256, a part number in the common 27C CMOS EPROM family, although the catalogue lists it as a schematic.
