Datasheet for the LM337, an adjustable three-terminal negative voltage regulator, the counterpart of the positive LM317.

BIOS image for project DKL50 on board LA-E802P revision 1.0, dated 2017-06-23, for an 8MB flash. The double OK tag in the name suggests a confirmed working dump.

Dell executable for the Alienware 16X Aurora, model code AC16251, version 2.7.0, most likely a BIOS update package run from Windows.

Small 65.1 KB PDF reference for the HEF4008BP, a CMOS logic device from the HEF4000 series that the 4008 number identifies as a four-bit full adder; the BP suffix…

The 2SD2634 transistor is described in this 30.7 KB PDF, classified as a schematic though the name points to a datasheet.

Datasheet for the 2SD1815 in PDF format, 154 KB, catalogued as a schematic. Apart from the type number, the name carries no extra details.

A 91.5 KB PDF titled with the JIS part number 2SD1886, which suggests a component datasheet even though the index tags it as a schematic.

Named 2SD1350_E, this 44.0 KB PDF sits in the schematic category but most likely holds the datasheet for the 2SD1350, an NPN low-frequency bipolar transistor under…

UTC datasheet covering the 2SD882L, a variant of the widely used 2SD882 NPN transistor, stored as a small PDF of about 24 KB.

The part number 2SC4473 is the only information in this 122 KB PDF name, and it identifies a Japanese JIS-coded NPN transistor of the high-frequency type.

At 153 KB, this PDF named 2SC4399 is presumably the datasheet for that NPN bipolar transistor, even though the index lists it as a schematic.

A 305 KB PDF for the 2SC4246 transistor. The name states nothing apart from the part number, so the manufacturer and revision have to be read inside the document.

A 468 KB PDF covering the 2SC3607 transistor, filed in the schematic category but best treated as a manufacturer datasheet.

Component reference for the 2SC3392, provided as a 155 KB PDF in the schematic category.

Only the part number 2SC3361 appears in the name of this 129 KB PDF, so no equipment or board can be identified from it.

A 94.9 KB PDF for the 2SC3088, filed as a schematic but in practice probably a component datasheet. Its name contains just the part number.

PDF of 42.0 KB covering the 2SB1392 transistor. The name provides only the part number; manufacturer, package and revision are not given.

The 2SA1564 is covered by this 90.3 KB PDF, which is labelled as a schematic but named after a discrete component.

Small PDF document for the 2SA1524, filed under schematics but by its name a component data sheet for a discrete transistor.

The 2SB857 transistor is covered in this 42.0 KB PDF, the same size as the 2SB858 file and probably from the same document series.

The 2SA1420 is the subject of this 91.5 KB PDF, which sits in the schematic section but by its naming is a part-level datasheet.

Component sheet for the 2SB779, delivered as a 40.5 KB PDF. It is catalogued as a schematic, though a name consisting of a bare part number indicates a datasheet.

The 2SB767 is covered by this 42.9 KB PDF, whose name adds only an _E suffix that cannot be decoded from the name alone.

PDF document for the TPS51117, a Texas Instruments single synchronous step-down controller frequently used for laptop system or memory rails; the file is catalogued as a…
