Part datasheet for the 2SD1782K, an NPN transistor named under the Japanese JIS scheme, with the K suffix indicating a particular variant or package.

This PDF of about 124 KB covers the 2SD2114 transistor with a KS suffix; the suffix is not explained by the name and may denote a gain class or package variant.

PDF covering the 2SD1880, about 88.9 KB, listed as a schematic but named after a single semiconductor part.

Reference PDF for the 2SK2711, about 140 KB, listed in the schematic category though the part number points to a discrete transistor datasheet.

Brief 34.7 KB PDF for the 2sk2581 transistor, catalogued as a schematic. JIS naming assigns 2SK to N-channel field-effect transistors, and the name gives no further…

Brief PDF, about 30.2 KB, for the 2SK2509, a JIS-designated N-channel FET as indicated by its 2SK prefix.

Document for the 2SK2400, 403 KB in PDF format and listed as a schematic, although the name points to a single-component datasheet.

PDF documentation for the 2SK1731 discrete semiconductor, roughly 90 KB in size. Japanese 2SK numbering identifies it as an N-channel FET; the name says nothing about…

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

Part documentation for the 2SJ337 in a 98.2 KB PDF. The file name names only this semiconductor, nothing about a device.

Reference sheet for the 2SD1062 transistor in PDF form, about 104 KB, catalogued under schematics.

A 126 KB PDF dedicated to the 2SC5257, sorted into the schematic section although the name identifies a single component.

PDF of about 63 KB for part 2SC4618, with a trailing h in the name whose meaning is not stated and may denote a variant or document version.

PDF of about 113 KB identified by the transistor number 2SC4403. The JIS prefix 2SC marks an NPN bipolar transistor, so this document should provide datasheet…

Component reference for the 2SC3963, supplied as a 193 KB PDF in the schematic category.

Short 40 KB PDF named for the 2SC4913 transistor. The 2SC prefix marks an NPN bipolar device under JIS registration, and the name carries no further detail about maker…

Part number 2SC5354 is all the name reveals about this 129 KB PDF, so it is not tied to any identified device.

PDF datasheet for the 2SB1594 transistor, about 187 KB, indexed as a schematic. In JIS numbering 2SB marks a PNP bipolar transistor for low-frequency applications; the…

PDF datasheet of about 175 KB for the 2SB1555, a PNP bipolar transistor under the Japanese JIS 2SB numbering for low-frequency devices.
