Part reference for the 2SK2953, a 431 KB PDF filed with schematics. The 2SK prefix places it in the Japanese JIS registry of N-channel FETs, meaning the content is a…

PDF reference sheet, 36.2 KB, for the 2SK1607. In the Japanese semiconductor naming scheme the 2SK series covers N-channel FETs, so this is a component datasheet even…

Specification sheet for the 2SC5276, a 136 KB PDF. The 2SC designation follows the Japanese JIS scheme for NPN bipolar transistors, so the document is probably the…

A 29.4 KB PDF covering the 2SC4710LS, a suffixed variant of the 2SC4710 number. Under JIS designation 2SC indicates an NPN bipolar transistor, and suffix letters usually…

Covering the 2SC4709, this 99.5 KB PDF is labelled a schematic but named for a single component.

A 94.1 KB PDF labelled 2SC4272, sitting in the schematic category but carrying only a part number, so it is probably the datasheet for that transistor.

Listed as a schematic, this 102 KB PDF is named after 2SC5042, which under Japanese JIS rules designates an NPN transistor, so a component datasheet is the likely…

A short 60 KB PDF for the 2SC2404, with an _E suffix in the name that is not explained there.

The 2SC2347 is the subject of this 292 KB PDF, filed as a schematic but most likely a datasheet for the NPN transistor.

Here is a 102 KB PDF named for the 2SA1764, placed in the schematic category, though JIS numbering identifies it as a PNP bipolar transistor and the document as its…

A 52.7 KB PDF for the 2SA1762 with an _E suffix, which in Japanese manufacturer document naming commonly indicates the English edition; no brand is stated.
