PDF for the BU4508DX, a small 48.8 KB document filed as a schematic but most likely the part datasheet.

The 2SK2035 transistor is the subject of this 295 KB PDF, most likely the manufacturer datasheet given that 2SK is the JIS prefix for N-channel FETs.

Document for the 2SK1806 in PDF format, 136 KB, catalogued as a schematic. The 2SK code marks an N-channel FET under JIS naming, so the contents are likely a component…

Filed under schematics, the 143 KB PDF named 2SJ509 most probably holds the datasheet for a single transistor, since 2SJ in the Japanese JIS scheme designates a…

Specification PDF, roughly 32 KB, for the 2SD667 transistor, listed among schematics but in fact a component datasheet.

Datasheet-style PDF for the 2SC4271 transistor, catalogued here under schematics and weighing 78.2 KB. The name gives only the part number, with no maker or revision.

A 107 KB PDF covering the 2SC4270, a JIS-numbered part. The 2SC prefix denotes an NPN transistor intended for high-frequency use.

Datasheet PDF for the 2SC5575, 52.0 KB, placed in the schematic section of the index. The file name contains only the part number.

Datasheet-style PDF for the 2SC3988, 114 KB, filed in the schematic category though the name is a plain JIS transistor number.

The 2SC3922 is the subject of this short 30.5 KB PDF, listed as a schematic with no suffix or revision in its name.

Covering the 2SC3914, this 30.1 KB PDF belongs to the family of JIS-numbered NPN bipolar transistors identified by the 2SC prefix.

Indexed as a schematic, this 195 KB PDF carries just the type number 2SC3803. In JIS semiconductor naming, 2SC stands for an NPN transistor, so the content is most…

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

Data for the 2SC3576, an NPN transistor per the JIS 2SC designation, supplied as a 108 KB PDF and filed among schematics.

Covering the 2SC3547A, this 288 KB PDF is a transistor datasheet indexed in the schematic section.

PDF document named after the 2SC5332 part number, filed here under schematics but most likely a component datasheet rather than a board diagram.

A 106 KB PDF for the 2SC3143, which the JIS 2SC designation marks as an NPN bipolar transistor.

Small PDF document for the 2SB1537, a Japanese JIS-registered transistor part number, catalogued here as a schematic although a part code like this normally points to a…

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.

PDF document of 196 KB identified only by the part number 2SA2058. Under the Japanese JIS convention, 2SA parts are PNP bipolar transistors, so this is almost certainly…

Datasheet-style PDF for the JEDEC part number 2N7224, 64.1 KB, catalogued as a schematic.

2N5400 transistor datasheet marked Sam, a 56.9 KB PDF that probably originates from Samsung, although the name alone cannot prove it.

A 61.3 KB PDF for the 1SV250, placed in the schematic category by the index. Following Toshiba's numbering, the 1SV group covers variable-capacitance diodes, so expect a…
