15 AMPERE COMPLEMENTARY SILICON POWER TRANSISTORS 60, 120 VOLTS 115, 180 WATTS

. . . PowerBase complementary transistors designed for high power audio, stepping motor and other linear applications. These devices can also be used in power switching circuits such as relay or solenoid drivers, dc–to–dc converters, inverters, or for inductive loads requiring higher safe operating area than the 2N3055 and MJ2955.
