Named after the 2SD2093, this PDF of 146 KB is most likely the component datasheet for that Japanese transistor.

This 91.1 KB PDF covers the 2SD1887 transistor; it sits in the schematic category but the file name matches a JIS component designation, pointing to a datasheet.

A 91.5 KB PDF titled with the JIS part number 2SD1886, which suggests a component datasheet even though the index tags it as a schematic.

A 40.8 KB PDF on the 2SK2012, an N-channel FET according to the JIS 2SK naming convention.

Part reference for the 2SK1452 in PDF form, 111 KB, classified as a schematic. The name states only the device number.

Reference sheet for the 2SD1313 transistor, stored as a 206 KB PDF and filed under schematics.

UTC datasheet covering the 2SD882L, a variant of the widely used 2SD882 NPN transistor, stored as a small PDF of about 24 KB.

Specification sheet for the 2SD874 transistor in PDF form, about 44 KB, catalogued with the schematics but actually a component datasheet.

Datasheet for the 2SD669 NPN transistor in a small 32 KB PDF, maker not stated in the file name.

At 188 KB, this PDF named 2SC4640 most likely holds the datasheet for that Japanese-standard NPN transistor. No equipment, board number or revision appears in the name.

At 153 KB, this PDF named 2SC4399 is presumably the datasheet for that NPN bipolar transistor, even though the index lists it as a schematic.

Filed as a schematic, this 59.7 KB PDF is titled 2SC5128 and presumably holds the datasheet of that NPN bipolar transistor.

Component documentation for the 2SC4269 in PDF form, 108 KB in size, listed in the schematic category. Nothing beyond the part number appears in the name.

PDF part sheet for the 2SC5577, 40.7 KB, catalogued with schematics. The name gives only the part number and says nothing about the maker or revision.

A 305 KB PDF for the 2SC4246 transistor. The name states nothing apart from the part number, so the manufacturer and revision have to be read inside the document.

At 108 KB, this PDF is labelled with the transistor type 2SC4221 and nothing else, so no board, model or revision is identified.

Covering the transistor 2SC4104, this compact 19.1 KB PDF is tagged as a schematic, but the 2SC prefix in Japanese JIS numbering identifies an NPN bipolar device, so…

Named only after the JIS transistor number 2SC3461, this 110 KB PDF is listed as a schematic but is most probably a single-part datasheet.

Component reference for the 2SC3392, provided as a 155 KB PDF in the schematic category.

Datasheet-style PDF named for the 2SC5322, 122 KB, though the catalogue labels it a schematic.

Datasheet-style PDF, 96.2 KB, named only for the 2SC3089 and catalogued as a schematic.

The 277 KB PDF named 2SC2878 sits in the schematic category, though the JIS 2SC prefix suggests a datasheet for an NPN bipolar transistor.

PDF reference for the 2SA1682, a part number following the Japanese JIS scheme in which 2SA identifies a PNP bipolar transistor of the high-frequency class.

PDF of 42.0 KB covering the 2SB1392 transistor. The name provides only the part number; manufacturer, package and revision are not given.

Datasheet in PDF format for the 2SA1579 transistor, 36.6 KB. Only the part number is given in the name.

A 59.2 KB PDF describing the 2sb1275 transistor, filed as a schematic though the name points to a single part.

A 55.0 KB PDF titled with the 2SA1531 part number and an _E suffix, catalogued as a schematic yet most plausibly the datasheet for that transistor.

Small PDF document for the 2SA1524, filed under schematics but by its name a component data sheet for a discrete transistor.

PDF reference of 143 KB for the 2SA1419, a JIS-numbered part whose 2SA prefix denotes a PNP transistor in the high-frequency class.

PDF datasheet for the 2SA1338, a part whose 2SA prefix marks it as a PNP transistor intended for high-frequency service under the Japanese JIS convention.

Datasheet PDF of only 13.5 KB for the 2SA684 transistor, marked UTC, which indicates the Unisonic Technologies edition of this part.

PNP transistor documentation for the 2SA1150, provided as a 193 KB PDF. JIS naming uses 2SA for PNP bipolar devices, so although indexed as a schematic the file almost…

Datasheet PDF, 149 KB, for the 2SA1710 transistor; the file name gives no further model or board details.

Part datasheet for the 2N5307, a 57.5 KB PDF classified as a schematic in this catalogue.

Labelled 80EPS08, this 80.7 KB PDF is classed as a schematic but carries a semiconductor part code in International Rectifier style, so it most likely contains a…

The 24WC257 is a Catalyst Semiconductor I2C serial EEPROM, and this 55.6 KB PDF, though catalogued as a schematic, is almost certainly its datasheet.

PDF document for the TDA7491P, a 1.45 MB file that is most likely the component datasheet rather than a board schematic, judging by the part-number name.

A 41.1 KB PDF titled with the part number 2SC1980 and an _E suffix, catalogued among schematics.

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