A compact 44.3 KB PDF describing the 2SD602 transistor, indexed as a schematic though its content is component data. An _E suffix appears in the name as an edition tag.

Single PDF of 40.8 KB for the 2SD2216, listed as a schematic but most likely a component datasheet, since the name is a part number rather than a board.

PDF document of 41.0 KB for the 2SD2185 transistor, with an _E suffix in the file name that is not decoded here.

Datasheet-style PDF for the 2SD1423, 41.0 KB, stored as a schematic; the trailing _E in the name is not explained by the file itself.

Reference PDF for the 3N255, sized at 42.2 KB and catalogued among schematics, though nothing beyond the part number is given in the name.

Component reference for the 2SD1993, a 45.5 KB PDF listed among schematics. Following Japanese JIS part numbering, 2SD identifies an NPN bipolar transistor of the…

The file, a 28.4 KB PDF, is named 2SK3485 and catalogued as a schematic; the name is a JIS semiconductor number, so treat it as a short datasheet.

Listed as a schematic, this 412 KB PDF carries only the part number 2SK2845 in its name.

Reference sheet for the 2SK2599 in a 418 KB PDF, placed in the schematic section although the name holds nothing but the part number.

Catalogued among schematics, the 43.5 KB PDF called 2SJ499's neighbour 2SJ485 refers to a semiconductor part; under the JIS scheme the 2SJ prefix designates a P-channel…

Brief 40.6 KB PDF for the 2SC4543, carrying an _E suffix whose meaning the name does not explain, and filed under schematics.

A 42.8 KB PDF for the 2SC5639, placed under schematics although its name is a bare part number pointing to a transistor datasheet.

Named simply 2SC4984, this 48.8 KB PDF is catalogued as a schematic yet points to a discrete semiconductor.

Labelled 2SC4835 with an _E suffix, this 41.5 KB PDF is filed as a schematic but refers to a JIS-numbered NPN transistor, indicated by the 2SC prefix.

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

Small 42 KB PDF for the 2SC3077, filed as a schematic. The trailing _E in the name is not explained by the file name itself.

Reference document for the 2SB1398 transistor, with an _E suffix in the name that is not explained and may indicate an edition or language version.

Datasheet PDF for the 2N7002, with an r2 tag in the name that most likely marks the second revision of the document; size 94.4 KB, listed in the schematic category.

Datasheet for the 2N2222A transistor, a 53.4 KB PDF whose name carries a Phi tag, most likely identifying the manufacturer edition.

The name points to the 1SV248 device, and the 60.4 KB PDF is filed as a schematic. Because 1SV is Toshiba's designation for variable-capacitance diodes, the document is…

Indexed as a schematic, this 68.4 KB PDF takes its name from the diode number 1SS372 and gives no device, board or brand information.

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

Datasheet for the 1N4937 diode, filed in the schematic category, a small 45.5 KB PDF. The 1N4933 to 1N4937 family are fast recovery rectifiers in an axial package, and…

No device or board appears in the name 161cmq, which instead looks like a dual Schottky rectifier family code; at 47.0 KB this PDF is probably a short datasheet, though…

At 43.6 KB, this PDF titled 152cmq030 is listed among schematics, yet the name is a rectifier part code for a common-cathode Schottky pair, commonly a 30 V grade.

A 553 KB PDF called simply 29040, indexed under schematics, which by its number most likely covers a 4 Mbit 29-series parallel flash memory datasheet; the manufacturer…
