PDF schematic for the PT10A AG Potomac 10A mainboard, MP build A03, dated 20080805, which makes it a later issue than earlier Potomac A03 sets. Packed as a 2.53 MB RAR.

The 2SC5540 transistor is covered by this 30.9 KB PDF, catalogued as a schematic. By JIS convention the 2SC prefix signifies an NPN bipolar device, so the document is…

Datasheet, 350 KB in PDF, for the 24AA08 and 24LC08B serial EEPROMs with 8 Kbit capacity on the I2C bus.

Filed under schematics, the 39.8 KB PDF 2SD2441 with an E tag refers by its JIS-style 2SD prefix to an NPN bipolar transistor.

PDF of 33.4 KB describing the 2SK2016 transistor, an N-channel FET by its JIS 2SK prefix. It is catalogued as a schematic but is best used as a component datasheet.

Part-number reference for the 2SC4433 in PDF form, about 71.5 KB. The name gives no board or device, only the JIS designation, where 2SC denotes an NPN bipolar…

Larger than most in this series at 474 KB, this PDF is for the 2SC5084, an NPN bipolar transistor according to the JIS 2SC prefix, catalogued here as a schematic.

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

A 179 KB PDF for the 2SC3670, an NPN bipolar transistor by its JIS-style 2SC prefix. The name gives only the part number, with no device, board or revision, so treat it…

Small 39.7 KB PDF for the 2SC3526, carrying an _E suffix in its name whose meaning, perhaps a language edition or document revision, cannot be confirmed from the name…

Compact 102 KB PDF for the 2SC3090 transistor, indexed under schematics. The name carries no detail beyond the part code.

Datasheet-style PDF, 317 KB, covering the 2SA1316 transistor even though the index type reads schematic.

A 229 KB PDF filed as a schematic, though its name, 25RIA, reads like a semiconductor part number rather than a board number, so the content is most likely a component…

Schematic diagram in PDF form for MSI motherboard MS-16881, revision 2.0 as given by the -20 suffix. MSI designs and numbers these boards itself.

A PDF reference sheet for the 2SD2259 transistor, catalogued as a schematic but in practice a component datasheet of 43.3 KB.

A 111 KB PDF for the 2SD2281, which under the Japanese JIS system is an NPN transistor from the low-frequency 2SD series.

A 166 KB PDF for the 2SD1904 transistor, listed here as a schematic but by its name almost certainly the manufacturer data sheet.

A compact 106 KB PDF covering the 2SK2919 transistor, indexed as a schematic though the name points to a manufacturer datasheet.

PDF document for the 2SK2374 part, filed under schematics but named after a Japanese-registered semiconductor rather than a board.

Small 30.0 KB PDF covering the 2SK2047 transistor. Under the JIS naming system the 2SK prefix marks an N-channel FET, so this is best treated as a part datasheet rather…

Datasheet-style PDF for the 2SK1840, sized 87.3 KB. Part numbers beginning with 2SK are registered under the Japanese JIS scheme for N-channel field-effect transistors.

The 2SK1489 named here is a discrete transistor code: under JIS numbering, 2SK denotes an N-channel field-effect transistor.

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

A 177 KB PDF describing the 2SC4689, placed in the schematic category of the catalogue.

Only the part number 2SC4168 identifies this 150 KB PDF, which carries a schematic label but is almost certainly a component datasheet.

This 105 KB PDF is named after the 2SC4159 and, although stored as a schematic, should contain the specification sheet for that NPN bipolar transistor, as the JIS 2SC…

Compact 125 KB PDF for the 2SC5091FT, an NPN bipolar transistor numbered under the Japanese 2SC scheme, with the FT suffix as part of the name; its exact meaning is not…
