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.
