Component data for the 2SD2130 NPN transistor, a PDF of about 209 KB. The name carries no board or device information; it is a part sheet following the Japanese 2SD…

This 244 KB PDF covers the 2SD2075A; the trailing A marks a variant of the base 2SD2075 type, though the name does not say how it differs.

An 88.2 KB PDF titled 2SD1884, indexed in the schematic section but, judging by the bare part number, a datasheet for that transistor.

The 3LP02SP part is documented in this 41.9 KB PDF, catalogued under schematics. The name gives only the component code; companion files 3LP02N and 3LP02M share the…

The 2SK2171 referenced in this 180 KB PDF is an N-channel field-effect transistor by JIS/EIAJ convention, which uses the 2SK prefix for that class.

PDF sheet for the 2SK1233 MOSFET, size 46.1 KB, part of the Japanese 2SK series of N-channel field-effect transistors.

A 196 KB PDF named for the 2SC4684 and listed in the schematic category. Its 2SC prefix is the JIS marker for NPN bipolar transistors, so the document is best read as a…

The 2SC4632LS gets a brief 26.9 KB PDF here, indexed as a schematic but named after a discrete semiconductor.

Datasheet PDF for the 2SC5229, 135 KB, kept in the schematic category of the index. Japanese JIS part numbering assigns 2SC to NPN bipolar transistors, which identifies…

Labelled 2SC4578, the 104 KB PDF is indexed as a schematic, though its name matches a single semiconductor part, so it is probably a datasheet.

Named simply 2SC4427, this 109 KB PDF documents a single semiconductor rather than a complete board.

The 2SC4423 is described by this 102 KB PDF, which the index lists as a schematic. Since 2SC is the JIS prefix for NPN bipolar transistors, the contents should be a…

This 246 KB PDF bears only the part number 2SC5110 and, despite its schematic label, should contain the datasheet for that device.

A compact 42.3 KB PDF named after the 2SC5444 transistor. Under JIS numbering, 2SC denotes an NPN bipolar device intended mainly for high-frequency use, so this is…

PDF for the 2SC5417LS, 43.1 KB, catalogued as a schematic. The LS letters after the number mark a variant of the base 2SC5417, which has its own sheet; compare both…

Covering the 2SC5416LS, this 43.0 KB PDF is the LS variant of the 2SC5416, which is documented in a companion file.

A 149 KB PDF carrying the bare transistor number 2SC4837. Though placed in the schematic category, the JIS prefix 2SC identifies an NPN transistor, so the file is…

Transistor number 2SC4824 is all the name of this 141 KB PDF reveals; the index places it among schematics.

PDF reference, about 124 KB, for the 2SC3776 transistor. The JIS 2SC prefix identifies an NPN bipolar part, so although the file is labelled a schematic it most likely…

Component documentation for the 2SC3669 in PDF format, 192 KB in size. The 2SC prefix in Japanese JIS numbering indicates an NPN bipolar transistor, and the bare…

Just under 100 KB, this PDF is identified only as 2SC3448 and catalogued as a schematic.

Datasheet PDF for the 2SC3311A, the A suffix denoting a variant of the base 2SC3311 number, filed under schematics at 40.5 KB.

Filed under schematics, the 146 KB PDF is named 2SC2883, a Japanese JIS designation for an NPN bipolar transistor.

Datasheet-style PDF, 38.3 KB, for the 2SC2631 transistor; the _E suffix may point to an English edition, though the name does not confirm it.

Part-number document for the 2SC2236, stored as a 178 KB PDF under the schematic category.

English-language edition, judging by the _E suffix, of a document for the 2SB1488 transistor, stored as a 46 KB PDF under schematics but almost certainly a datasheet.

Reference sheet for the 2SA1624 transistor, saved as a 128 KB PDF and indexed in the schematic category.

PDF of 54.3 KB documenting the 2SB1322A, the A suffix marking a variant of the base 2SB1322 part. Catalogued as a schematic, it actually describes one transistor.
