Richtek marking-code reference in PDF format. Richtek power ICs, including PWM controllers, buck converters, LDOs and load switches, are very common on laptop…

PDF table of Linear Technology marking codes, intended for identifying LT parts from the abbreviated top marks printed on small packages.

For the 2SK1609 transistor, this 36.6 KB PDF supplies the component data. Under Japanese JIS/JEITA conventions 2SK identifies an N-channel FET; the name carries no…

Specification sheet, 85.3 KB in PDF form, for the 2SD1958 NPN transistor, indexed in the schematic section.

Covering the 2SC4523, this 90.3 KB PDF is a semiconductor data sheet rather than a board schematic, despite its catalogue category.

Short 26 KB PDF named 5HN01SS, filed as a schematic yet describing a single small component. The SS suffix likely marks the most compact package in the 5HN01 range.

PDF of 135 KB for the 2SC5277, filed as a schematic but most likely a transistor datasheet, as 2SC is the JIS prefix for NPN bipolar devices.

Spanish PDF titled Microelectrónica, 4.14 MB, with no device, brand or board named. It is likely training or course material covering microelectronics topics such as…

Reference sheet for the 2SD2550 transistor, a PDF of roughly 239 KB catalogued as a schematic.

PDF documentation, around 108 KB, for the 2SD2150 NPN transistor under the Japanese 2SD numbering system.

Reference datasheet for the 2SK1052, delivered as a 104 KB PDF with no other details in the name.

Small PDF of 26.5 KB named 5HP01SS, listed as a schematic yet evidently referring to a single semiconductor part rather than a board.

Transistor datasheet for the 2SD2155, stored as a 177 KB PDF and filed with schematics.

The 2SA1435 is the subject of this 29.8 KB PDF, and the file name gives nothing beyond the part number.

PDF datasheet, 178 KB, for the 2SA1804 transistor. In Japanese JIS numbering a 2SA part is a PNP bipolar transistor, and this document should provide its voltage…

PDF reference sheet for the 2SD1682 transistor, 150 KB, stored in the schematic category.

At 466 KB, this PDF for the 2SC4325 sits under schematics, yet the name is a bare transistor part number, so expect a component datasheet.

Documentation in PDF for the 2SA1832F, a suffixed version of the 2SA1832, 231 KB in size and indexed as a schematic.

A 30.6 KB PDF for the 2SK3278, indexed as a schematic but holding component reference data.

A 144 KB PDF whose name is just the part number 2SD1190, filed as a schematic but in practice a transistor datasheet.

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.

Combined PDF, 53.0 KB, whose name lists two part numbers, 2SB1189 and 2SB1238, suggesting one data sheet covering both transistors. It is filed as a schematic.

PDF reference for the 2SA1807 transistor, 43.9 KB, listed as a schematic but in practice a component datasheet.

A PDF of 129 KB indexed as a schematic, though the name 6CWQ03FN reads like a discrete semiconductor part number rather than a board number, so it is most likely a…

Indexed under schematics, this 83.0 KB PDF is named 12tts08, a code that resembles International Rectifier or Vishay thyristor (SCR) part numbering.

Spanish microelectronics course in PDF form, 4.14 MB, without any specific device, brand or board named.

Named 2SK3491, this 29.8 KB PDF is most likely the datasheet for that JIS-numbered device, despite being listed as a schematic.

The 121 KB PDF labelled 2SC4598 sits in the schematic section, yet the name is a discrete component number, so expect a datasheet.

PDF datasheet, 41.0 KB, for the 2SC5506 NPN bipolar transistor, held in the schematic section.

A 103 KB PDF named only after the part 2SC3992, indexed as a schematic but in practice almost certainly a transistor datasheet.

PDF of 30.1 KB covering the 2SA1520, listed as a schematic yet named like a single-part data sheet. JIS numbering places 2SA parts among PNP bipolar transistors.

Reference PDF of 42.8 KB for the 2SB956 semiconductor, marked with an _E suffix whose meaning the name does not give.

Part-number document for 2SA2056, stored as a 191 KB PDF and listed in the schematic section.

Datasheet PDF of 60.8 KB covering the 2N3904, one of the most commonly found JEDEC part numbers in general-purpose circuits.

Filed under schematics, though the file name is simply the JIS part number 2SD1903, so expect a component datasheet in this 131 KB PDF.

Datasheet-style PDF for the 2SK3018, indexed here under schematics, though the 2SK prefix marks a Japanese JIS-registered N-channel field-effect transistor rather than a…

Part number 2SC4454 gives this 101 KB PDF its name, and the index places it in the schematic group.

At 511 KB, the largest in this run of files, a PDF referenced by the transistor number 2SC2714 and filed as a schematic.
