Lenovo firmware package for the GYG41 / GYG51 platform built on LCFC board NM-D131, revision 1.0, with the name dated 27 July 2020.

Labelled 2SD2526, this 192 KB PDF contains reference data for a Japanese-coded transistor rather than a device-level circuit.

Component datasheet in PDF form, 57.8 KB, for the 2SD1478, though the index files it under schematics.

Short 36.3 KB PDF on the 2SK1803. Part numbers prefixed 2SK are N-channel field-effect transistors in the Japanese JIS registration system, and this file is most likely…

Documentation for the 2SJ378 P-channel FET in a 418 KB PDF, listed as a schematic though really a datasheet.

A 136 KB PDF for the 2SC4616, listed among schematics though the name only carries a component part number, implying a transistor datasheet.

Datasheet for the 2SC4214 transistor, supplied as a 279 KB PDF. The file name holds nothing beyond the part number, so the manufacturer, package and target equipment…

PDF document of 331 KB named after the 2SC4116 part number, filed in the index under schematics.

The 2SC4108 is the only detail this 94 KB PDF name provides, and the index files it as a schematic.

The 2SC5404 is covered by this 319 KB PDF, which the index files as a schematic. The name carries only the transistor number.

Small 46 KB PDF covering the 2SC5383, a part number in the JIS 2SC series used for NPN bipolar transistors.

Around 173 KB of PDF datasheet material for the 2SC5307, an NPN bipolar transistor in the Japanese JIS 2SC series. The name gives no maker, package or intended circuit.

A 96.0 KB PDF for the 2SC3687 transistor, placed in the schematic category of the index. According to the Japanese JIS system, the 2SC prefix means NPN bipolar.

Named simply 2SC3447, this 97.5 KB PDF appears under schematics but is most likely the transistor's datasheet.

Reference datasheet for the 2SB1617 PNP transistor, supplied as a 213 KB PDF. Following Japanese JIS numbering, 2SB parts are PNP bipolar transistors for low-frequency…

For the 2SA1356, this 177 KB PDF carries just the part number, so it is most probably the device datasheet rather than a full circuit diagram.

Covering the 2SA1242, this 212 KB PDF carries only the part number in its name, so it is best treated as the component datasheet despite the schematic label.

Largest sheet in this group at 469 KB, this PDF for the 2N5962 is listed as a schematic, though it is likely a detailed datasheet with graphs.

PDF datasheet of about 125 KB covering the 2SD1766 NPN transistor, part of the Japanese JIS 2SD numbering.

PDF documentation for the 2SK772, size 77.7 KB. Within the Japanese JIS numbering scheme, 2SK identifies N-channel field-effect transistors, so the content is most…

An 87 KB PDF for the 2SC2412K, an NPN transistor named under the Japanese JIS convention with a K suffix.

A small 43 KB PDF named after the 2SC2344 NPN transistor, part of the Japanese JIS 2SC series.

The name offers nothing beyond the 2SD2500 part number, and the 250 KB PDF is almost certainly that transistor's datasheet.

The 2SD1628 is covered in this 88.3 KB PDF, catalogued with schematics though it relates to a single transistor.

Datasheet-type PDF of 31.1 KB for the 2SK3412 semiconductor, stored under the schematic category.

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 2SK1890, documented in a 96.7 KB PDF placed in the schematic category. Japanese JIS numbering reserves 2SK for N-channel FETs, so this is a component datasheet…

Covering the 2SK1435, this 105 KB PDF is indexed as a schematic yet named after one discrete component, which suggests a datasheet.
