Registered ratings are 60V collector-emitter, 100V collector-base, 15A continuous collector current, 115W dissipation and a DC current gain of 20 to 70 at 4A. Its complementary PNP device is the MJ2955, and the two are commonly paired in push-pull output stages. The NTE and ECG aftermarket cross-reference house number for the 2N3055 is NTE130 \/ ECG130. Note that some variants such as the 2N3055H and 2N3055HV carry different voltage ratings — confirm the specific manufacturer's datasheet before substituting.
