10/11/22, 12:27 KT315 - Wikipedia KT315 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 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 massproduction launch of the KT315 were awarded the USSR State Prize for it in 1973.[1][2] Contents Application See also КТ315 А...И Structure n-p-n Uce 15–60 V Ube 6V Ic 50–100 mA Ib 50 mA P 100 mW Pmax 150 mW Tmax, °C up to 100 °C fT 250 MHz h21e 20–350 References External links Application KT315 transistors were designed for use in high-, medium- and sound-frequency amplifying stages.
