Datasheet PDF, 60 KB, for the 2SD1650, with the name given in lowercase and filed under schematics.

The 3N248 is covered by this 43.6 KB PDF, indexed under schematics but named only by its JEDEC part number.

Brief 34.7 KB PDF for the 2sk2581 transistor, catalogued as a schematic. JIS naming assigns 2SK to N-channel field-effect transistors, and the name gives no further…

Small 33.8 KB PDF on the 2sk2495, a part number in the JIS N-channel FET series marked by the 2SK prefix.

For the 2SK2313 transistor, this 419 KB PDF is filed as a schematic but is expected to be a datasheet, since 2SK is the JIS prefix for N-channel FETs.

The file name gives nothing beyond 2SK2233, a JIS/EIAJ designation whose 2SK prefix marks an N-channel field-effect transistor.

A 96.5 KB PDF identified only as 2SK1889 and filed under schematics. Under the JIS scheme the 2SK prefix indicates an N-channel field-effect transistor, so the file most…

PDF datasheet, 173 KB, covering the 2SK1740. The 2SK series in JIS nomenclature consists of N-channel FETs, and this document is likely its specification sheet.

PDF documentation for the 2SK1731 discrete semiconductor, roughly 90 KB in size. Japanese 2SK numbering identifies it as an N-channel FET; the name says nothing about…

For the 2SK1470, a Japanese-coded N-channel field-effect transistor, this 97.9 KB PDF serves as component reference material even though it sits in the schematic…

Reference document for the 2SK1436 transistor, supplied as a 105 KB PDF and listed under schematics.

PDF covering the 2SK1104, an N-channel FET identified by the 2SK prefix of the Japanese semiconductor numbering system.

Datasheet-type PDF for the 2SK536, 60.8 KB, catalogued under schematics. Under the Japanese JIS system the 2SK designation means an N-channel FET, so the content…

Covering the 2SJ589LS, this 33.2 KB PDF is catalogued as a schematic, though the name points to a component datasheet.

Here is a 151 KB PDF for the 2SD1230, filed under schematics although it relates to one transistor type.

For the 2SD1011, this 42.1 KB PDF carries an _E tag in the name with no stated meaning.

Unisonic Technologies (UTC) specification sheet for the base 2SD882 NPN transistor, supplied as a 22 KB PDF.

Here is a 144 KB PDF for the 2SC4728, filed as a schematic but carrying a discrete part number.

Small 37.9 KB PDF for the 2SC4715, with an _E suffix in the name whose meaning is not stated, possibly a language or document edition marker.

Here is the 2SC5242 documentation as a 173 KB PDF, placed in the schematic category but evidently a part datasheet going by its name.

PDF of about 63 KB for part 2SC4618, with a trailing h in the name whose meaning is not stated and may denote a variant or document version.

Listed as a schematic, this 103 KB PDF is titled with the device code 2SC4461. In the JIS semiconductor naming scheme, 2SC stands for an NPN bipolar transistor meant for…

Named 2SC5569 and weighing 50.3 KB, this PDF sits in the schematic category but refers only to a transistor part number.

Datasheet PDF of 125 KB for the 2SC4854, placed under schematics in the index. Only the part number is given in the name.

Datasheet for the 2SC3613, a 241 KB PDF listed among schematic files although its content is a single-component specification.

Specification document for the 2SC3515 transistor, a 225 KB PDF placed in the schematic category.

The 140 KB PDF is identified only by the transistor number 2SC3393 and contains no board or model reference.

Datasheet PDF of 248 KB for the 2SC3138, an NPN bipolar transistor going by its Japanese JIS 2SC prefix.

Small 42.4 KB PDF for the 2SC2634, carrying an _E suffix that may mean an English edition, though the name does not state it.

Indexed as a schematic, this 199 KB PDF actually carries only the part number 2SC1959, pointing to a single NPN bipolar transistor under the JIS naming scheme.

PDF datasheet of about 175 KB for the 2SB1555, a PNP bipolar transistor under the Japanese JIS 2SB numbering for low-frequency devices.

Component reference for the 2SB1386, a 155 KB PDF that likely holds full electrical tables, though the name states nothing beyond the part number.

PDF of 90.6 KB for the 2SB1131, listed in the schematic category though the name is simply a component number.

Compact 29.9 KB PDF for the 2SA2063 transistor, indexed as a schematic but serving as component data.

A 58.9 KB PDF for the 2SA1964, with a 1-2 tag in the name whose meaning is not stated; it may indicate pages or an edition.
