Datasheet for the 2SD2131 transistor, provided as a 240 KB PDF in the schematic section.

The 2SD1800 transistor is covered by this 79 KB PDF datasheet. Under JIS numbering, 2SD denotes an NPN transistor for low-frequency service, often used in switching…

Listed as a schematic, this 89.6 KB PDF is named 2SD1883 and is most likely the corresponding transistor datasheet rather than a circuit drawing.

Compact 25.2 KB PDF named for the 3SK301, categorised as a schematic but most likely a part datasheet. Nothing besides the type number appears in the name.

At 178 KB, this PDF for the 2SK3020 is one of the fuller documents in the group, listed as a schematic but serving as a datasheet.

Covering the 2SK2991, this 420 KB PDF is named only by part number, which points to an N-channel field-effect transistor in the Japanese JIS numbering system.

Reference sheet for the 2SK2844 transistor, stored as a 427 KB PDF and catalogued under schematics.

Documentation for the 2SK2624LS, provided as a 42.8 KB PDF in the schematic category. The 2SK part of the number is the JIS designation for N-channel field-effect…

Transistor reference for the 2SK2543, supplied as a 410 KB PDF and filed under schematics.

For the 2SK2417 there is this 400 KB PDF, placed in the schematic category but, judging by the JIS-style number, a transistor datasheet; 2SK marks N-channel FETs.

Part 2SK2377 is documented in a 31.7 KB PDF placed in the schematic category. Under Japanese JIS designations a 2SK prefix denotes an N-channel field-effect transistor…

This 55 KB PDF is labelled 2SK2220 and indexed under schematics, though a part-number name usually means the datasheet of a single semiconductor.

Indexed as a schematic, this 422 KB PDF is titled 2SK2201 and most likely contains the datasheet for that part.

Although stored as a schematic, this 409 KB file named 2SK2173 most likely contains a component datasheet.

A 121 KB PDF named 2SK2170, listed among schematics but most likely the datasheet for that single device.

Catalogued under schematics, this 121 KB PDF titled 2SK2167 most likely holds the datasheet for that transistor.

The name carries only the part number 2SK2127, an N-channel FET designation in the Japanese JIS system.

Indexed as a schematic, this 129 KB PDF concerns the 2SK2095N, where the N may mark a variant of the base 2SK2095 part.

A 111 KB PDF for the 2SK1453, placed among schematics, although the part-number naming points to a component data sheet.
