The KT315 is a Soviet silicon NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications, enclosed in the plastic KT-13 package. It was widely used in Soviet electronic equipment. The KT361 is a complementary (PNP) for the KT315 transistor, so it was often paired with it in push-pull stages.

KT315 and KT361 transistors became the first[when?] in the USSR, which were produced using planar technology. The characteristics achieved in the KT315 were groundbreaking in Soviet technology at that time. The process of manufacturing was much cheaper than the alloy-junction technology, and the parameters surpassed those of earlier transistor types, in particular, the unity-gain frequency was 250 MHz.
The people associated with the development and mass-production launch of the KT315 were awarded the USSR State Prize for it in 1973.[1][2]
Application
editKT315 transistors were designed for use in high-, medium- and sound-frequency amplifying stages.
