PDF of 51.8 KB for the 2SC5610 transistor, indexed with schematics although the bare part number suggests a manufacturer datasheet.

A 249 KB PDF for the 2SC4203, filed as a schematic but named with only a semiconductor type number.

The 2SC5459 comes as a 186 KB PDF in the schematic category, though the part number, a JIS 2SC NPN transistor, points to a datasheet.

Small 28.7 KB PDF for the 2SC5699 transistor. Per JIS convention, the 2SC prefix identifies an NPN bipolar device, so the file is likely a short datasheet.

This 106 KB PDF carries the part number 2SC5044 and is catalogued as a schematic. Since the 2SC prefix in the Japanese JIS system marks NPN transistors, the content is…

The 102 KB PDF 2SC5041 is indexed under schematics, though its name is just a 2SC part number, the Japanese JIS code for an NPN bipolar transistor, so treat it as a…

Specification sheet for the JIS-designated 2SC3952 NPN bipolar transistor, provided as a 41.0 KB PDF and filed with schematics.

The 2SC3938 sheet arrives as a 46.3 KB PDF with an _E suffix, which on Japanese component documents typically signals an English edition.

Listed as a schematic, this 118 KB PDF is named only 2SC4863 and is most likely a component datasheet.

Datasheet-type PDF for the 2SC3912, sized at 30.2 KB. The part number follows the JIS standard, where 2SC identifies an NPN bipolar transistor; the name offers no…

The 2SC3901 transistor is documented in this 88.3 KB PDF. Following the JIS convention, the 2SC prefix denotes an NPN bipolar device, so the file is most plausibly its…

A 126 KB PDF documenting the 2SC3773 transistor, an NPN device under the JIS 2SC designation.

Component documentation for the 2SC5375 transistor, packaged as a 122 KB PDF. Following JIS registration, the 2SC prefix designates an NPN bipolar device; the name…

PDF covering the 2SC5301 transistor. Under the JIS designation system the 2SC prefix marks an NPN bipolar device.
