PDF reference sheet for the 2SC5243, 46.0 KB in size and indexed as a schematic, although the name suggests a transistor datasheet.

PDF file of roughly 104 KB identified only by the part number 2SC4424. Under the Japanese JIS numbering scheme, 2SC parts are NPN bipolar transistors, so the document…

Compact 32.8 KB PDF labelled 2SC5645, filed among schematics but most probably a single-part datasheet for that transistor.

The largest of this group at 465 KB, the PDF named 2SC4394 is most likely a full datasheet for that transistor rather than a board schematic, despite its index label.

Filed under schematics, this 117 KB PDF is named for the 2SC5563, a part number following the Japanese convention in which 2SC marks an NPN bipolar transistor.

Datasheet PDF, 373 KB, for the 2SC752TM transistor, listed in the schematic section. The 2SC prefix identifies a JIS-registered NPN bipolar device, and TM is part of the…

Named 2SC3940 with an _E suffix, this 51.7 KB PDF sits in the schematic index but is a transistor datasheet by all appearances, the suffix usually denoting an English…

At 31.1 KB, this compact PDF for the 2SC4976 is filed as a schematic, though the part-number name indicates a component sheet.

Reference sheet in PDF format, 101 KB, for the 2SC4852 NPN transistor, named under the Japanese JIS convention where 2SC denotes NPN bipolar parts.

PDF document of 96.1 KB tied to the 2SC3896 transistor, named under the JIS standard in which 2SC indicates an NPN bipolar part.

A 185 KB PDF for the 2SC5331 transistor, indexed as a schematic although the part-number title points to a datasheet.

A 320 KB PDF dealing with the 2SC3123, an NPN bipolar transistor by its Japanese JIS 2SC code.

A 98.8 KB PDF covering the 2SC3039, listed as a schematic and likely a datasheet in practice. The name contains only the part code.

A 320 KB PDF dedicated to the 2SC3011, indexed as a schematic but most likely a transistor datasheet. Nothing besides the part number appears in the name.

A 58.1 KB PDF for the 2SA1552, catalogued as a schematic though the name indicates a single transistor.

The 2SA1539 part number gives this 41.0 KB PDF its name, and although it is filed under schematics it almost certainly holds the datasheet for that transistor.

The 2SB906 transistor is the subject of this 196 KB PDF. Following JIS designation, 2SB parts are PNP bipolar transistors classed for low-frequency use.

Covering the 2SB834, this compact 11.9 KB PDF carries a UTC tag that most likely refers to Unisonic Technologies, a maker that produces many second-source versions of…

PDF reference for the 2SA1203, 99.3 KB, sorted among schematics although the bare part-number name points to a datasheet.

A compact 31.6 KB PDF covering the 2SA1857, listed under schematics but most likely a component datasheet.

Datasheet for the 2SA970, supplied as a 321 KB PDF, the largest in this group, which suggests it includes detailed characteristic curves.

Filed under schematics, this 173 KB PDF is named after the 2SA965, a part number in the Japanese JIS scheme where the 2SA prefix marks a PNP bipolar transistor, so it is…

PDF reference for the 2N3820, only 26.3 KB, likely a short one- or two-page data sheet, although the index files it as a schematic.

Filed among schematics, this 91.7 KB PDF is named 2764 with nothing else to identify brand or board.

PDF of 119 KB named 27C256B, filed as a schematic yet clearly a part number from the 27C CMOS EPROM line, here with a B revision letter.

A 171 KB PDF named 27c010, categorised as a schematic, though the number marks it as a part from the 27C CMOS EPROM line. No device, brand or board appears in the name.

Base datasheet for the 25tts series, saved as a 232 KB PDF and catalogued as a schematic.
