Schematic archive catalogued under Samsung and named only A12, presumably the Galaxy A12 handset, though the name does not confirm the variant.

PDF of 536 KB for the Atmel AT93C46, a small serial EEPROM using the Microwire-style three-wire interface.

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.

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…

Component data for the 2SD2130 NPN transistor, a PDF of about 209 KB. The name carries no board or device information; it is a part sheet following the Japanese 2SD…

This 244 KB PDF covers the 2SD2075A; the trailing A marks a variant of the base 2SD2075 type, though the name does not say how it differs.

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

The only detail in this 183 KB PDF name is the part number 2SD2461, indicating the datasheet for that transistor.

Datasheet-style document, 133 KB in PDF format, covering the 2SD1681 part number and listed as a schematic.

A compact 30.6 KB PDF tied to the 2SD1666 part number, catalogued among schematics. In Japanese JIS designations, 2SD stands for an NPN bipolar transistor meant for…

Transistor sheet for the 2SD1626, 87.9 KB in PDF format, filed as a schematic. In JIS codes, 2SD denotes an NPN bipolar device for low-frequency or power circuits.

A 53.3 KB PDF for the 2SD2071, with an E suffix in the name whose meaning is not stated.

Very small 22.2 KB PDF relating to the 2SD1999, filed as a schematic. The name offers nothing but the part code, which follows the JIS scheme where 2SD denotes an NPN…

PDF documentation, 32.7 KB, for the 3SK269, indexed under schematics. The JIS code 3SK marks an N-channel field-effect transistor with four terminals, generally a…

The 3SK263 is covered by an 82.7 KB PDF placed in the schematic category, though a part-number name like this normally indicates a component datasheet.

The 3LP02SP part is documented in this 41.9 KB PDF, catalogued under schematics. The name gives only the component code; companion files 3LP02N and 3LP02M share the…

Part documentation for the 2SK3292 in PDF format, 33.3 KB, catalogued under the schematic type. The 2SK code follows the Japanese JEITA convention for N-channel FETs.

Part documentation for the 2SK2731, a 113 KB PDF placed in the schematic category. JIS naming assigns the 2SK prefix to N-channel field-effect transistors, so the…

Component datasheet for the 2SK2661, a 385 KB PDF that is indexed as a schematic. Under JIS naming, the 2SK prefix marks an N-channel field-effect transistor, so look…

A 30.5 KB PDF for the 2SK2631, filed among schematics though the number is a JIS N-channel FET designation, meaning the content is a component datasheet.

Catalogued as a schematic, this 31.8 KB PDF is named 2SK1443LS, pointing to a suffixed variant of the 2SK1443. The name does not clarify the LS suffix.

For the 2SK1427 N-channel FET, this 101 KB PDF sits in the schematic section of the index but most likely contains a datasheet.

45.9 KB PDF documenting the 2SK1235 N-channel MOSFET, a JIS-registered Japanese part number.

Component reference for the 2SK1214 N-channel MOSFET, a 34.3 KB PDF in the Japanese 2SK family.

PDF documentation, 42.4 KB, for the 2SD1010 part, with an unexplained _E suffix in its name.

The 2sc4725 is the subject of this 56.8 KB PDF, categorised as a schematic. Since 2SC is the JIS designation for NPN bipolar transistors, the document is most probably…

At 28.7 KB, this PDF for the 2SC4634LS is likely a condensed datasheet for a package variant of the 2SC4634 NPN transistor.

PDF datasheet, 89.5 KB, for the 2SC4633 transistor, though the index files it under schematics.

The 2SC4630 is documented in this 95.5 KB PDF, which the index labels a schematic although the name points to a datasheet.

Labelled 2SC4578, the 104 KB PDF is indexed as a schematic, though its name matches a single semiconductor part, so it is probably a datasheet.

Transistor 2SC4458 is the subject of this 103 KB PDF, which the catalogue lists as a schematic.

The 2SC4423 is described by this 102 KB PDF, which the index lists as a schematic. Since 2SC is the JIS prefix for NPN bipolar transistors, the contents should be a…

This 246 KB PDF bears only the part number 2SC5110 and, despite its schematic label, should contain the datasheet for that device.
