Russian-language PDF on the marking of electronic components, as the transliterated title Markirovka elementov REA indicates, filed under schematics but really a general…

An 88.0 KB PDF for the 2SD1838, a Japanese-registered NPN bipolar transistor, best treated as a datasheet even though it is indexed as a schematic.

Datasheet for the 2SD2271 transistor, a 219 KB PDF and one of the larger files in this 2SD group, so it probably includes detailed characteristic curves.

A 143 KB PDF catalogued as a schematic, covering the 2SD1801 semiconductor part. Under the Japanese JIS numbering system the 2SD prefix marks an NPN bipolar transistor…

Reference sheet for the 2SD2116 NPN transistor, supplied as a 74 KB PDF. Its name follows the Japanese JIS 2SD convention and carries nothing beyond the part number.

Reference document for the 2SD1662 transistor, 137 KB, PDF format, placed in the schematic category.

The 3SK304 is covered by this 25.9 KB PDF, listed as a schematic though it is expected to be a component datasheet.

PDF reference for the 2SK2993 transistor, 424 KB. The file name carries only the part number, which under the JIS scheme denotes an N-channel field-effect transistor, so…

Very small 26.9 KB PDF for the 2SK2951, likely a short datasheet or summary page given its size.

A 134 KB PDF identified solely as 2SK2219, placed in the schematic category but most likely a transistor datasheet.

This 96.1 KB PDF is named 2SK2161 and placed with schematics, but a part-number title like this usually signals a single-device datasheet.

Listed among schematics, this 97.3 KB PDF is named for the 2SK1887. Japanese JIS designations starting 2SK belong to N-channel field-effect transistors, so expect…

PDF of 101 KB for the 2SK1849 transistor, listed with schematics. In JIS numbering the 2SK prefix identifies an N-channel FET, so this should be the device datasheet…

Named only 2SK1463, this 121 KB PDF is grouped with schematics but concerns a discrete part: the Japanese 2SK prefix means an N-channel FET.

A small 98.7 KB PDF about the 2SK1416, catalogued under schematics but most likely a component datasheet.

Small 29.4 KB PDF bearing only the part number 2sj146. The 2SJ prefix in Japanese JIS naming designates a P-channel field-effect transistor, so treat this as a compact…

A 420 KB PDF covering the 2SJ402, whose 2SJ prefix under Japanese JIS designation marks a P-channel field-effect transistor.

A 320 KB PDF for the 2SJ380, catalogued under schematics but by its number a transistor datasheet. In JIS designation, 2SJ parts are P-channel field-effect transistors.

PDF file of about 148 KB describing the 2SJ315, listed in the schematic section. No board or brand is mentioned, only the part number.

The 2SJ312 is documented in this 362 KB PDF, catalogued as a schematic. Beyond the part number the name says nothing about the equipment involved.
