PDF reference for the 2SD1852, a 2SD-series NPN bipolar transistor, about 96.5 KB and more likely a component datasheet than a circuit diagram.

Short 44 KB PDF covering the 4N32 and 4N33 optocouplers, two closely related members of the 4N family that use a Darlington phototransistor output for high current…

Revision 5 of a datasheet for the 4N25 optocoupler, a 281 KB PDF. The 4N25 is one of the oldest and most common phototransistor-output isolators, often found in power…

One of the larger sheets in the set at 271 KB, this PDF is named after the 2SD2498 and serves as a transistor datasheet.

This 145 KB PDF carries the 2SD1722 part number and nothing more, so it is best treated as that transistor's datasheet.

Covering the 2SD2067, this 60 KB PDF carries an E suffix that the name leaves unexplained.

Component sheet for the 2SK2614, delivered as a 172 KB PDF. Within JIS numbering, 2SK marks an N-channel field-effect transistor, so the document presents ratings…

PDF sheet for the 2SK1233 MOSFET, size 46.1 KB, part of the Japanese 2SK series of N-channel field-effect transistors.

A 297 KB PDF describing the 2SC4251 transistor. The name contains just the part number, so the issuing manufacturer and revision must be read inside the document.

Component sheet for the 2SC4209 in PDF format, 187 KB. The original name contains just the part number, so details like package, maker or revision are absent.

At 411 KB, this PDF for the 2SC5717 is one of the larger documents in the set and is probably a complete datasheet with graphs.

Datasheet-style PDF, 42.2 KB, for the 2SC3829 transistor, carrying an _E suffix whose meaning the name does not explain, possibly an edition or language tag.
