Small transistor heat sink.

4 5 out of 5 stars 54. In analog applications of semiconductors heat will most often be encountered in voltage regulators and output transistors. The heat is not a problem if i c is small or if the transistor is used as a switch because when full on v ce is almost zero. However power transistors used in circuits such as an audio amplifier or a motor speed controller will be partly on most of the time and v ce may be about half the supply voltage.
