Datasheet in PDF for the MUR1560, an ultrafast recovery rectifier diode. The 15 in the part number indicates 15 A and the 60 indicates 600 V, a common choice for output…

Datasheet in PDF for the KSC3503, an NPN transistor; the file name gives only the part number, so ratings must come from the document.

Datasheet for the IRF840 N-channel MOSFET, delivered as a 282 KB PDF. Typical contents include maximum drain-source voltage, continuous current, on-resistance…

Reference for the BU2508AX, provided as an 81.1 KB PDF catalogued as a schematic, which is most likely the component datasheet.

Datasheet for the BC557 small-signal PNP transistor, a 45.8 KB PDF that matches the size of the other BC557 files in this collection.

The 5LP02N is covered by this 42.2 KB PDF, catalogued as a schematic but most likely a component datasheet.

Small PDF of 27.3 KB for the 3LN01N, catalogued as a schematic though the name reads as a discrete transistor part number, so it is most likely a datasheet.

At only 34.4 KB, this PDF is a short reference for the 2SD1913 transistor. Under Japanese JIS part numbering the 2SD prefix identifies an NPN device for low-frequency…

The 42.4 KB PDF is named for the 2SD2345 and carries an _E suffix, whose meaning the name does not explain.

Catalogued as a schematic, this 156 KB PDF is named after the 2SD1906, a Japanese JIS part number, so it is most likely the component datasheet for that transistor…

PDF for the 2SK2299N, 137 KB, carrying an extra _1-5 suffix in the name whose meaning is not stated; it may mark an alternate edition or page range.

Compact 30.7 KB PDF covering the 2SJ628, catalogued as a schematic but most likely a single-device datasheet given the part-number name.

Identified solely as 2SJ257, this 96.0 KB PDF most likely documents a P-channel FET, the device class assigned the 2SJ prefix in the JIS system.

Component datasheet for the 2SD882S transistor as published by UTC (Unisonic Technologies), filed here under schematics although it is a part specification rather than a…

OPPO R7s repair archive in RAR format, 1.29 MB in size. The name gives no detail beyond the model, so open it with WinRAR or 7-Zip to see whether it holds schematics, a…

Catalogued as a schematic, this small 46.1 KB PDF is in practice a component document for the 2SC4755, a part number that follows the Japanese JIS scheme, where the 2SC…

Filed as a schematic, this 120 KB PDF is named only after the part number 2SC4402, so it is most likely the manufacturer datasheet for that transistor rather than a…

A 98.4 KB PDF titled with the part number 2SC4162, filed under schematics but in practice expected to be the datasheet for that transistor.

PDF reference sheet for the 2SC3184, filed in the index as a schematic but named after a single part number in the Japanese JIS scheme.

Small 40.7 KB PDF named 2SC2925 with an added _E suffix, classified here as a schematic.

Component datasheet for the 2SB1434 transistor, filed under schematics but in practice a part reference rather than a board diagram.
