Datasheet for the 2SD669 NPN transistor in a small 32 KB PDF, maker not stated in the file name.

A small 49.5 KB PDF for the 2SC4767 part, filed as a schematic; the trailing _E in the name is not explained, so check the document to see what it denotes.

Part number 2SC4223 is all the file name gives, so this 93.9 KB PDF is best treated as a datasheet for that component rather than a circuit schematic.

Small 44.2 KB PDF for the 2SC5541, filed as a schematic though the part code points to an NPN bipolar transistor under the Japanese JIS system.

Listed under schematics, this 36.9 KB PDF belongs to the 2SC5538, which the Japanese JIS prefix identifies as an NPN bipolar transistor.

A small 28.7 KB PDF identified only by the code 2SC5680, a number of the Japanese 2SC family of NPN bipolar transistors.

Small 30.8 KB PDF covering the 2SC3919, one of a numbered run of similar sheets in this index.

Short 27.5 KB PDF for the 2SC3751 NPN transistor, the smallest file in this group, so it is probably a brief specification or summary sheet.

A small 44.6 KB PDF named 2SC5310, filed under schematics though the title is a transistor part number.

Small 42.8 KB PDF for the 2SC2188, carrying an _E suffix in its name and filed under schematics.

PDF for the 2SB1340 with a _1-2 suffix, 58.3 KB, filed among schematics yet describing a single transistor; the suffix may indicate a part or revision of the document…

Small PDF document for the 2SA1524, filed under schematics but by its name a component data sheet for a discrete transistor.

Small PDF of 42.0 KB covering the 2SB1030, with an _E suffix that may mark a document edition, though the name does not say.

Small 41.8 KB PDF for the 2SB792, filed as a schematic but named only after a part number, so it is most likely the component datasheet.

Datasheet in PDF form for the 2SA1018 transistor, filed in the index under schematics, with an E suffix in the name that likely marks a document edition or variant.

Plain 2N7002 datasheet in PDF form, 94.6 KB, indexed under schematics. The name carries no maker, package suffix or revision, so check the first page for the vendor.

A short 46.2 KB PDF named 2N6668, indexed as a schematic although its title is only a JEDEC discrete semiconductor number. No host device or board is given.

Small 26.3 KB PDF datasheet for the 2N5246 semiconductor device. The name only gives the part number, without manufacturer, package or revision.

Filed as a schematic, this small PDF of 60.3 KB is named only with the part code 1T410 and gives no device, brand or board number.

Single-part PDF for the 1SV325, indexed as a schematic and roughly 70 KB in size. The 1SV series is a JIS-registered diode family that Toshiba uses for…
