Power transistor(and other power devices) must dissipate a large amount of internally generated heat. For BJT ppwer transistors, the collector terminal is the critical junction; for this reason, the transistor's case is alwasy connected to to the collector terminal. The case of all power transistors is designed to provide a large contact area between it and an external heat sink. Heat from the transistor flows through the the case to the heat sink and then dissipates in the surrounding air. Heat sinks vary in size, number of fins, and type of material. Their size depends on thhhhe heat dissipation requirement and the maximum ambient temperature in which the transistor is to operate. In high-power applications (a few hundred watts), a cooling may be necessary.(p.428)
