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. A 2SD designation in the JIS scheme identifies an NPN bipolar transistor for low-frequency use. Expect electrical characteristics, a package drawing and pin assignment rather than a circuit diagram. When replacing the device, confirm that the full marking matches, since suffix letters can change the package or the gain grouping.
