Schematic PDF for the Bitland BM5688 board, a design from the ODM Bitland, which builds laptops and tablets for various brands.

Reference document for the 2SD2249, a part in the JIS 2SD family of NPN low-frequency bipolar transistors, saved as a 45.3 KB PDF.

At 312 KB, this PDF for the 2SD2638 is the largest in its series and is probably a full datasheet with curves and outline drawings, though it is filed under schematics.

Datasheet-style PDF for the 5LP02SP, about 42.2 KB and placed in the schematic category.

A 27.1 KB PDF titled with the part code 5LP01SS, stored in the schematic category but evidently a small datasheet.

Part reference for the 3N250, stored as a PDF of about 43.6 KB and catalogued in the schematic section.

Part reference for the 2SK2862 in a 411 KB PDF, listed under schematics in this index. The name carries only the transistor number.

Datasheet-style PDF of 21.4 KB for the 2SK2751, listed under the schematic category. The 2SK designation belongs to the Japanese JIS system and marks an N-channel…

Component document for the 2SK2745 in PDF form, 399 KB, filed as a schematic. Because 2SK is the Japanese JIS prefix for N-channel field-effect transistors, the file…

PDF of 33.4 KB describing the 2SK2016 transistor, an N-channel FET by its JIS 2SK prefix. It is catalogued as a schematic but is best used as a component datasheet.

Datasheet-style PDF for the 2SK1840, sized 87.3 KB. Part numbers beginning with 2SK are registered under the Japanese JIS scheme for N-channel field-effect transistors.

An 88.5 KB PDF on the 2SK1738 transistor. In the JIS system, 2SK designates an N-channel FET, so this file is most likely the datasheet rather than a circuit schematic.

For the 2SK614, a part number from the JIS family of N-channel field-effect transistors, this 32.7 KB PDF is catalogued as a schematic but is most plausibly a short…

Filed under schematics, the 143 KB PDF named 2SJ509 most probably holds the datasheet for a single transistor, since 2SJ in the Japanese JIS scheme designates a…

Nothing beyond the code 2SJ272 is given in the name of this 92.3 KB PDF. Japanese JIS numbering assigns the 2SJ prefix to P-channel field-effect transistors, so the…

Part-number reference for the 2SC4433 in PDF form, about 71.5 KB. The name gives no board or device, only the JIS designation, where 2SC denotes an NPN bipolar…
