The transistor 2N3055 is packaged in a TO3 case. It has its collector "grounded" to the case, and the base and emitter to the two pins. NPN transistors are usually used with the emitter going directly to the ground, and the collector somewhere far from the ground. Can someone give me a typical application for this 2n3055 transistor, showing how it is typically used in a circuit? What am I missing? The MJ2955, its mating PNP, is the same way, and this, in a PNP makes sense. Thanks for your help.
