PDF document for the 2SC4435, catalogued as a schematic but named after a discrete semiconductor part number rather than a board.

Datasheet-type PDF of about 90.7 KB for the 2SC4413. No board, brand or revision appears in the name; the JIS 2SC prefix simply indicates an NPN bipolar transistor.

A 187 KB PDF named after the 2SC4408 part number and listed in the schematic category. JIS numbering uses 2SC for NPN bipolar transistors, so treat the file as a…

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.

Part number 2SC4223 is all the file name gives, so this 93.9 KB PDF is best treated as a datasheet for that component rather than a circuit schematic.

Datasheet-style PDF, 95.3 KB, for the 2SC4222 transistor. It is indexed as a schematic, but the name holds only the part number.

Filed in the schematic section, this 156 KB PDF is named for the 2SC4135, which by JIS convention is an NPN bipolar transistor, so expect a component datasheet inside.

Part number 2SC4124 names this 98.7 KB PDF, which is labelled a schematic but, given the JIS-style designation for an NPN bipolar transistor, should be that part's…

PDF document of 300 KB named after 2SC5093, a Japanese-registered NPN bipolar transistor part number, filed in the index under the schematic category although the name…

Small 44.2 KB PDF for the 2SC5541, filed as a schematic though the part code points to an NPN bipolar transistor under the Japanese JIS system.

Listed under schematics, this 36.9 KB PDF belongs to the 2SC5538, which the Japanese JIS prefix identifies as an NPN bipolar transistor.

The 2SC5526 is documented in this 52.6 KB PDF, placed among schematics in the index. By Japanese JIS convention a 2SC part is an NPN bipolar transistor, so the file…

A small 28.7 KB PDF identified only by the code 2SC5680, a number of the Japanese 2SC family of NPN bipolar transistors.

PDF for the 2SC4061K, 61.7 KB, filed under schematics though the name reads as a component datasheet.

The 2SC3996 is covered by this 91.9 KB PDF, sorted under schematics although a name consisting only of a part code usually means a datasheet.

Part 2SC3991 is the only information carried by this 113 KB PDF, which the index lists as a schematic although the name points to a discrete component datasheet.

PDF sheet for the 2SC3935 part, with an _E suffix after the number, filed under schematics at 40.7 KB.

A 126 KB PDF for the 2SC4871, given with only the part number and filed in the schematic section.

Component datasheet for the 2SC4868, provided as a 123 KB PDF and filed as a schematic. The name states only the part number.

The 2SC4867 is documented in this 127 KB PDF, which sits in the schematic category. No board, model or revision appears in the name.

The 2SC4861 datasheet appears to be what this 117 KB PDF contains, although it is filed in the schematic category. Only the part number is stated.

Covering the 2SC3811, this 45.7 KB PDF has an _E suffix in its name, which is not explained and may denote an edition or English version.

At 469 KB, this PDF carries just the transistor designation 2SC4844 and is filed in the schematic category.

Filed under schematics, this 466 KB PDF is identified by the code 2SC4839 alone. In the Japanese JIS designation system the 2SC prefix belongs to NPN bipolar…

Only the type number 2SC4836 appears in the name of this 110 KB PDF, indexed as a schematic.

Short 27.5 KB PDF for the 2SC3751 NPN transistor, the smallest file in this group, so it is probably a brief specification or summary sheet.

Specifications for the 2SC3656 in PDF form, 90.4 KB. Parts beginning with 2SC in the JIS system are NPN bipolar transistors.

Datasheet in PDF form, 289 KB, for the 2SC3547B, filed with schematics. The B suffix marks a variant of the 2SC3547; the name alone does not say whether it denotes a…

Datasheet for the 2SC3495 in a 91.6 KB PDF, indexed in the schematic category. By Japanese JIS naming, the 2SC prefix identifies an NPN bipolar transistor designed for…

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.

Named simply 2SC3399, this 86.9 KB PDF refers to a Japanese-registered NPN transistor; the 2SC prefix under JIS indicates a high-frequency type.

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

Only the part number 2SC3361 appears in the name of this 129 KB PDF, so no equipment or board can be identified from it.

The 152 KB PDF is labelled 2SC5355, a Japanese JIS transistor designation in which 2SC identifies an NPN device of the high-frequency category.
