Named for the 2SD2462, this 184 KB PDF is effectively a datasheet for a Japanese-registered transistor.

PDF of 184 KB bearing the part number 2SD1410A, kept in the schematic category but best treated as the transistor's datasheet, with the A suffix denoting a variant of…

Filed as a schematic, this 72.9 KB PDF is titled 2SD1398; in the Japanese JIS scheme the 2SD prefix marks an NPN bipolar transistor intended for low-frequency use, so…

A 195 KB PDF labelled with the transistor type 2SC4210. No device, board or manufacturer is named; the 2SC prefix simply tells us, through the Japanese JEITA system…

Indexed as a schematic, this 96.7 KB PDF is named for the 2SC3086 and most likely holds that transistor's datasheet.

Reference PDF of 176 KB for the 2SA1425 transistor, carrying no information in its name beyond the part number.

The 2SA1352 is the only identifier in this 149 KB PDF name, so treat it as the transistor datasheet even though the index calls it a schematic.

Portuguese-language PDF guide whose title translates to How to Test Electronic Components, 620 KB in size.

Base Wistron JV50 schematic set in revision RSB, archived as a 1.55 MB RAR. The name gives no laptop brand and no variant suffix, which separates it from the TR, TR8 and…

Datasheet-style document for the 2SD2581 transistor, saved as a 43.7 KB PDF and filed in the schematic category.

Compact 42.8 KB PDF for the 2SD2537, listed as a schematic though the name points to a single-component datasheet.

The 2SD2079 PDF, 219 KB in size, is indexed as a schematic yet corresponds to a single discrete component.

The name offers nothing beyond the 2SD2500 part number, and the 250 KB PDF is almost certainly that transistor's datasheet.

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

Part number 2SD1424 with an unexplained _E suffix names this 41.4 KB PDF, indexed among schematics but most likely a datasheet for the transistor.

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…

A 398 KB PDF for the 2SK2034, a part in the Japanese 2SK series of N-channel field-effect transistors.

Reference sheet for the 2SK937 transistor, a 79.9 KB PDF. Parts in the 2SK range are N-channel field-effect transistors under the Japanese JIS designation.

A 155 KB PDF bearing the part number 2SC4734 and nothing else. The 2SC prefix belongs to the JIS/JEITA system for NPN bipolar transistors, so despite the schematic label…

PDF of about 113 KB identified by the transistor number 2SC4403. The JIS prefix 2SC marks an NPN bipolar transistor, so this document should provide datasheet…

The 2SC5567 transistor is the subject of this 49.6 KB PDF, which the catalogue lists as a schematic.

A 99.4 KB PDF for the 2SC3779 transistor. The file name gives only the part number; the 2SC prefix follows the Japanese JIS scheme for NPN transistors, so this is almost…

Datasheet-style PDF for the 2SC5386 transistor, filed under schematics in this index. The 2SC prefix follows the old JIS convention for NPN transistors intended for…

Covering the 2SC3150 transistor, this 103 KB PDF sits in the schematic category of the index.

PDF reference for the 2SA1574 transistor, 47.9 KB in size. Apart from the part number, the name says nothing about package, maker or revision.

PDF reference sheet for the 2sb1236 transistor, 52.0 KB. The file name carries the part number only, with no further detail.

Component documentation for the 2SB745 transistor, supplied as a 55.4 KB PDF; the trailing _E in the name is not explained.

Schematic PDF for the ASUS FX505DY gaming laptop, 8.02 MB, without a revision stated in the name.

Only the part number 2SD2088 appears in the name of this 171 KB PDF, so treat it as the datasheet for that transistor.

Here is the 389 KB PDF for the 2SK1359 MOSFET, part of the Japanese 2SK family of N-channel field-effect transistors.
