Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic ta ...
NPN bipolar junction transistor
A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor, uses only one kind of charge carrier. A bipola ...

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 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
The USSR State Prize (russian: links=no, Государственная премия СССР, Gosudarstvennaya premiya SSSR) was the Soviet Union's state honor. It was established on 9 September 1966. After the dissolution of the Soviet Union, t ...
