Reference sheet for the 2SD2550 transistor, a PDF of roughly 239 KB catalogued as a schematic.

A 277 KB PDF covering the 2SD2539, a part number in the JIS 2SD family, which denotes NPN bipolar transistors for low-frequency circuits.

PDF of about 179 KB for the 2SD2531, filed as a schematic but probably the component datasheet.

A 27 KB PDF named 5HN01M, filed under schematics but referring to a single discrete component. The M suffix most likely denotes a package within the 5HN01 series.

PDF documentation, around 108 KB, for the 2SD2150 NPN transistor under the Japanese 2SD numbering system.

Datasheet for the 2SD1784 transistor in PDF format, roughly 153 KB, listed among schematics. The 2SD designation marks an NPN low-frequency device under the JIS system.

Transistor reference for the 2SD2048, 78.9 KB, in PDF format and listed among schematics.

A 107 KB PDF titled with the lowercase part number 2sd1565, catalogued as a schematic yet almost certainly a transistor datasheet.

Datasheet-type PDF for the 3SK271, around 32.7 KB, catalogued in the schematic category.

A 173 KB PDF covering the 2SD2386, an NPN bipolar transistor by its JIS 2SD designation, listed in the schematic section.

A 201 KB PDF for the 2SD2353, indexed in the schematic category, though the part number points to a component datasheet.

Datasheet PDF for the 2SD1512, 40.8 KB, catalogued in the schematic section. The JIS prefix 2SD denotes an NPN bipolar transistor of the low-frequency type, and the E…

PDF datasheet of 137 KB for the 2SK3120, sorted into the schematic category of the index.

The 2SK3092 is described in this compact 31.3 KB PDF, catalogued as a schematic but acting as a datasheet. Under JEITA designations, a 2SK part is an N-channel FET.

Datasheet for the 2SK2968 in a 405 KB PDF, categorised with schematics but describing one discrete device.

A 417 KB PDF on the 2SK2967 transistor. The name gives only the part code, and 2SK designates an N-channel FET in the Japanese JIS scheme, so this is a component…

Covering the 2SK2952, this PDF of 414 KB is a discrete transistor document rather than a full circuit, as the JIS 2SK prefix indicates an N-channel field-effect…

A 413 KB PDF for the 2SK2699 transistor, filed as a schematic in this index. The 2SK prefix identifies it as a JIS-registered N-channel field-effect transistor, so the…

A 139 KB PDF for the 2SK2623, which JIS numbering identifies as an N-channel FET. Although indexed as a schematic, it is effectively a component datasheet with limits…

Document for the 2SK2493 field-effect transistor in PDF form, 384 KB, listed under schematics in the catalogue.

Reference sheet for the 2SK2382, a 412 KB PDF placed under schematics, though the JIS-format number marks it as a datasheet for an N-channel FET.

A short 28.8 KB PDF for the 2SK2379, indexed as a schematic though it is almost certainly a component datasheet; JIS numbers starting with 2SK denote N-channel…

Titled 2SK2378, this 26.7 KB PDF is the smallest in its series and is listed under schematics, but the JIS part number indicates a datasheet for an N-channel FET.

Covering the 2SK2095N N-channel field-effect transistor, this 128 KB PDF is catalogued under schematics but is presumably a datasheet.

The 2SK2094 N-channel FET is the subject of this 127 KB PDF, which is catalogued as a schematic though the bare part-number name points to a datasheet.

The name pairs the 2SK2078 with STW9NA80, an STMicroelectronics-style part number, so this 133 KB PDF may cover both devices or present one as an equivalent.

Reference sheet in PDF form (98.9 KB) for the 2SK1909 transistor, catalogued under schematics.

Small 36.4 KB PDF for the 2SK1614, an N-channel field-effect transistor according to the Japanese 2SK designation.

PDF datasheet, 117 KB, for the 2SK1460, a Japanese-designated N-channel field-effect transistor, filed under schematics in the catalogue.
