Part number : KT315
Functions : NPN bipolar junction transistor
Package information : KT-13
This is a Soviet 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.
This transistors were designed for use in high, medium and sound frequency amplifying stages.
