Small Transistor Heat Sink

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.

Small transistor heat sink.

If you have a 12 volt supply and wish do generate an output of 5 volts using a regulator then with a circuit drawing one amp of output current the. For small transistors the clip on star type heat sinks illustrated in fig. 8 28 a may be used. Heat sinks take many different forms such as finned aluminium or copper sheets or blocks often painted or anodised matt black to help dissipate heat more quickly.
