PDF table of Linear Technology marking codes, intended for identifying LT parts from the abbreviated top marks printed on small packages.

PDF titled only with the part number D304X, about 489 KB, filed as a schematic. The name gives no further detail on device type or manufacturer, so the contents are most…

A 194 KB PDF describing the 2SD2604A, listed as a schematic but most likely a transistor datasheet.

Compact 29.7 KB PDF for the 2SD2649, placed in the schematic section though the name indicates a component datasheet.

The 2SD2648 is covered by this 29.0 KB PDF, indexed as a schematic but in practice a single-device reference.

Reference PDF of 40.9 KB for the 2SD1819A, with an E tag in the name that probably denotes an English-language edition, filed under schematics.

Component reference for the 5LP02C, a 42.3 KB PDF that the index lists as a schematic. The name carries just the part code, where the LP letters appear to mark a…

A 28.0 KB PDF classed as a schematic whose name, 3LP01C, reads as a component part code ending in C. The file name gives no device, board number or manufacturer.

Datasheet PDF of 413 KB for the 2SK2866 transistor, catalogued under the schematic type. Only the part number is stated in the name.

Compact 23.1 KB PDF named only with the part number 2SK2277. Because 2SK is the JIS prefix for N-channel FETs, the schematic category here most likely holds a short…

PDF reference, 35.6 KB, for the 2SK2276, a Japanese JIS-registered device where the 2SK prefix indicates an N-channel field-effect transistor.

Small 33.2 KB PDF covering the 2SK1478, written in lowercase in the original name. The 2SK prefix belongs to the Japanese semiconductor designation for N-channel…

Indexed as a schematic, this 112 KB PDF carries just the name 2SK1454, a JIS-style code for an N-channel field-effect transistor.

The 2SK690 is named here, and the 2SK prefix marks a Japanese-registered N-channel FET, so this 32.6 KB PDF is best treated as a part datasheet even though it is filed…

Listed under schematics, this 94.5 KB PDF carries only the designation 2SJ276. Under the JIS system the 2SJ prefix belongs to P-channel FETs, so the file is almost…

Bearing only the part code 2SJ264, this 101 KB PDF relates to a P-channel FET, as the JIS 2SJ prefix designates that transistor type.

Only the transistor number 2SJ259 appears in the name of this 99.0 KB PDF. JIS coding uses 2SJ for P-channel FETs, which suggests a datasheet even though the file is…

Part documentation for the 2SD1196 in a 139 KB PDF, placed in the schematic category but evidently a component datasheet given its name.

Here is a compact 94.6 KB PDF named for the transistor type 2SC4660. The name points to the part itself rather than any board or appliance.

The 2SC4250 transistor is documented in this 347 KB PDF, listed among schematics in the index.

The 2SC4030 transistor is documented in this 119 KB PDF, which is listed in the schematic section.

The 2SC3747 transistor is covered by this 95.9 KB PDF, categorised as a schematic but by its name a datasheet for a single component.

Component datasheet for the 2sb1580, 64.2 KB in PDF and indexed as a schematic. The 2SB prefix comes from the JIS standard and indicates a PNP bipolar transistor for…

Datasheet for the 2SB1539 PNP transistor as a 40 KB PDF; the _E suffix most likely marks the English edition of the document.

An 86 KB PDF covering the 2SA1896, a PNP bipolar transistor under the Japanese JIS 2SA designation.

Short 31.2 KB PDF for the 2SA1864, a PNP bipolar transistor in the Japanese JIS 2SA family.

Component PDF of 133 KB for the 2SA1705, filed as a schematic but named after the part only, with no device or board information.

PDF reference of 51.6 KB named 2N1613, placed in the schematic category. The 2N prefix follows the JEDEC numbering used for discrete semiconductors, so the content is…
