Compact 33.8 KB PDF describing the 2SK758, an N-channel field-effect transistor in the JIS 2SK series.

Indexed as a schematic, this 33.9 KB PDF for the 2SK655 is best read as a transistor datasheet, since 2SK numbers designate N-channel FETs under the Japanese JIS…

Datasheet PDF, roughly 82.3 KB, for the 2SK222, catalogued among schematics. The JIS 2SK series denotes N-channel field-effect transistors, and the name supplies no…

Datasheet document, by all indications, for the 2SJ189, a JIS-registered P-channel FET, held as an 83.5 KB PDF in the schematic section.

Brief 41.5 KB PDF on the 2SD1211 with an _E suffix, entered in the schematic category. Under JIS conventions the 2SD prefix stands for an NPN bipolar transistor for…

Small 98.3 KB PDF for the 2SC5300 part. The 2SC prefix is the Japanese JIS registration for NPN bipolar transistors, so despite being listed as a schematic, the file is…

Component sheet for the 2SC4615 NPN transistor, around 154 KB in PDF format and filed as a schematic.

Small 41 KB PDF for the 2SC5190, with an _E suffix that may denote an English-language edition, though the name does not state this.

Indexed under schematics, the 116 KB PDF named 2SC5155 refers to a discrete semiconductor rather than a whole board.

Only the part number 2SC4563 identifies this 85.4 KB PDF, categorised as a schematic but best treated as a datasheet for a JIS-designated NPN bipolar transistor of the…

A 90.4 KB PDF identified solely by the code 2SC4451. Under Japanese JIS semiconductor naming, the 2SC prefix marks an NPN transistor of the high-frequency type, so this…

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…

Plain 2SC5111 is the whole name of this 245 KB PDF, filed in the schematic section yet most likely the transistor datasheet.

106 KB PDF tied to the 2SC4204 transistor, with no other information in the file name. The JEITA 2SC prefix denotes an NPN bipolar device, so despite the schematic label…

Part 2SC5048 is the only detail in the name of this 210 KB PDF, classed here as a schematic.

The 2SC3951 PDF, 41.1 KB, is indexed as a schematic but is named purely after a JIS transistor part, so treat it as a datasheet for an NPN bipolar device.

Datasheet-style PDF, 42.2 KB, for the 2SC3829 transistor, carrying an _E suffix whose meaning the name does not explain, possibly an edition or language tag.

Reference sheet for the 2SC4805 NPN transistor, stored as a compact PDF of about 40 KB with an _E suffix that probably indicates an English edition.

Datasheet-style document for the 2SC3778 NPN transistor, stored as a 126 KB PDF under the schematic label.

At 217 KB, this PDF for the 2SC3673 is one of the larger documents in the 2SC367x group and is indexed as a schematic.

Transistor data in a 215 KB PDF named 2SC3376, catalogued as a schematic. The 2SC prefix belongs to the Japanese JIS scheme and marks an NPN device intended for…

A 169 KB PDF carrying only the part number 2SC5319, which by the JIS system identifies an NPN bipolar transistor.

The 330 KB PDF here carries the part number 2SC2551, a JIS-registered NPN transistor designation.

PDF file of 231 KB for the 2SA1586, catalogued as a schematic but named after one discrete semiconductor.

Datasheet in PDF form for the 2SA1562 transistor, 95.5 KB. The name gives no equipment, board or manufacturer information.

Part number 2SA1533 names this 51.3 KB PDF, with an unexplained _E suffix; despite the schematic category it is presumably the transistor datasheet.

At 95.1 KB this is one of the larger files in the set, a PDF named after the 2SB1205 transistor and indexed as a schematic, though it is presumably the datasheet.

The 2SA1438 transistor is described in this 133 KB PDF, which the index files under schematics.

Transistor datasheet for the 2SA2070 in PDF format, roughly 189 KB. The 2SA prefix places it in the JIS category of PNP transistors for high-frequency use.

For the transistor 2SA2039 this 40.2 KB PDF most likely provides the manufacturer datasheet, even though it sits in the schematic category.
