These power transistors will almost certainly need a heat sink to prevent them overheating. In analog applications of semiconductors heat will most often be encountered in voltage regulators and output transistors. Get it as soon as fri sep 25. Heat sink in transistor must be used to increase the area in contact with the atmosphere.

Apply a small amount of the thermal paste to the transistor flat side slip the heat shrink tubing over the metal tab then carefully slide the transistor in being sure the flat side contacts the heatsink shrink the tubing to complete. Heat sinks are available at mouser electronics from industry leading manufacturers. For higher power transistors sheet metal and aluminum extrusion heat sinks are available as illustrated in fig. Get it as soon as thu sep 24.

With regulators the power lost to heat is pretty easy to conceptualize. For small transistors the clip on star type heat sinks illustrated in fig. 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. A heat sink is designed to remove heat from a transistor and dissipate it into the surrounding air as efficiently as possible.
