Firmware dump for a 16-channel DVR built on board AHB70XXT16-3531 version 2.01B, with a label of AHD-7016T-LM and ID 50, provided as an 11.9 MB RAR.

Circuit diagram of the Toshiba PA-1750-09 power adapter, built around an LTA601N controller, noted in the name as a TEA1751T equivalent; the Russian phrase means on the…

Here is the 2SD1825 in PDF format, 150 KB, listed under schematics though the name suggests a transistor datasheet rather than a circuit diagram.

Documentation for the 2SA1402 transistor, a 119 KB PDF indexed in the schematic section.

The 2SK1606 N-channel field-effect transistor is described in this 36.7 KB PDF, the 2SK prefix following Japanese JIS/JEITA registration.

PDF of 173 KB for the 2SC4707, sorted into the schematic category. Because 2SC is the JIS/JEITA designation for NPN bipolar transistors, expect a component datasheet…

PDF datasheet of 101 KB for the 40CTQ150, listed under schematics. The CTQ series covers dual common-cathode Schottky rectifiers, and the 150 code points to a higher…

Photo archive for the Quanta G3MQ board, a large 73.7 MB RAR file of board images. High-resolution PCB photos help with comparing component placement, spotting missing…

Component PDF for the 2SA1688, roughly 150 KB, catalogued as a schematic although its plain JIS part number matches a datasheet.

PDF of 105 KB for the 2SA1606, indexed among schematics yet covering a single semiconductor.

Datasheet in PDF form for the 2SA1321 transistor, about 213 KB, filed in the schematic category.

PDF component sheet, 173 KB, named for the 2SK2969. Under the Japanese JIS numbering a 2SK part is an N-channel FET, which makes this a transistor datasheet despite its…

Named simply 2SC4636, this 103 KB PDF documents that Japanese-standard NPN transistor and is most likely its datasheet. The name gives no appliance or board reference.

A 98.2 KB PDF named 2SC4634 documents that NPN bipolar transistor and is presumably its datasheet. An LS-variant document sits alongside it in the collection.

For the 2SC5703 there is this 167 KB PDF, catalogued as a schematic but almost certainly a part datasheet, since 2SC denotes an NPN bipolar transistor in the JIS system.

Reference sheet for the 2SA1391, supplied as a 237 KB PDF and listed among schematics. Following JIS convention, the 2SA prefix means a PNP transistor for high-frequency…

Archive named EC, 8.63 MB, with no device, brand or board number given. The name hints at embedded controller firmware, which manages power-on, charging, keyboard and…

PDF of 129 KB for the 2SD1427, an NPN bipolar transistor in the 2SD series, indexed as a schematic but most likely a datasheet. The name gives no ratings or package.

Datasheet for the 2SC4600 transistor, a 115 KB PDF filed within the schematic category.

Covering the 2SC5198, this 171 KB PDF sits in the schematic category but carries only a transistor part number, so treat it as a datasheet.

A 171 KB PDF for the 2SC5196 transistor, grouped under schematics although the name points to a datasheet.

Reference sheet for the 2SA1689 in PDF format, 74 KB, indexed as a schematic despite a file name that indicates a standard transistor datasheet.

Datasheet-type document in PDF for the 2SA1687, a Japanese JIS-registered transistor, listed under schematics at 143 KB.

PDF reference of 188 KB for the 2SA1680, a Japanese-registered transistor; the name offers no manufacturer, package or revision details.

Covering the 2SA1407, this 108 KB PDF is a part reference stored in the schematic category.

For the 2SA1392, this 174 KB PDF provides the part reference, categorised as a schematic although the name points to a single transistor.

PDF datasheet of roughly 194 KB for the 2SA2065 transistor, catalogued among schematics.

ROM file called amiboot, 512 KB, whose name hints at an AMI BIOS image but gives no board, model or version. The 4 Mbit size suggests an older desktop or embedded board.

2.1 amplifier schematic built around the TDA7294, by Technical Mriganka, in a 219 KB PDF.

RAR archive of 87.4 MB with a generic name indicating motherboard images. No brand, model or board number is stated, so the contents must be inspected to see which…

Small Excel spreadsheet titled GDDR6X, the graphics memory type used on higher-end recent graphics cards.

Reference PDF for the 2SC4602, around 119 KB, placed in the schematic category. Nothing in the name refers to a device or board, so treat it as a component datasheet for…

Part documentation for the 2SC4601 transistor, supplied as a 115 KB PDF and indexed as a schematic.
