Component datasheet for the 2SD2137, a part from the Japanese 2SD series, which designates NPN bipolar transistors intended for low-frequency use.

PDF named 2SD951, filed as a schematic but in all likelihood the datasheet for this 2SD-series NPN bipolar transistor; at 267 KB it may include scanned pages or extra…

The 2SD2210 appears in this 46.9 KB PDF with an E suffix in the name that is left unexplained.

Reference PDF, 218 KB, for the 2SD2584 component, indexed under schematics. In Japanese JIS numbering, 2SD indicates an NPN bipolar transistor designed for low-frequency…

Stored under schematics, this 171 KB PDF is named 2SD1407A and is most probably the datasheet for that transistor variant, the A suffix distinguishing it from the base…

Component documentation for the 2SK2996 in PDF form, 412 KB in size. The 2SK designation identifies an N-channel field-effect transistor registered under the Japanese…

Component PDF, 409 KB, for the 2SK2964. In the Japanese JIS designation system a 2SK number refers to an N-channel FET, so treat the file as a transistor datasheet even…

Concise 37.7 KB PDF for the 2SK2464, filed among schematics yet named after a single semiconductor.

Carrying only the designation 2SK2200, this 413 KB PDF is listed with schematics yet most likely documents one transistor.

About 90 KB in size, this PDF carries only the 2SK2091 part number and is likely the datasheet for that N-channel field-effect transistor, despite being filed as a…

PDF datasheet, 113 KB, for the 2SK1690, which the Japanese 2SK numbering identifies as an N-channel FET.

NEC datasheet in PDF form for the 2SK1584, 57.9 KB, with the manufacturer given directly in the file name.
