KD503 are packaged in a TO-3 case style (called T41 by Tesla). It is a 20 amp, 80 volt, 150 watt power transistor. It has a transition frequency of 2.0 MHz.
The KD503 have higher power and higher current than 2n3055.[2] They were used extensively in the former Eastern Bloc countries in audio power amplifiers made by Czechoslovakian Tesla and Polish Unitra.
