Aluminum Heat SinkTO-220

The Aluminum Heat SinkTO-220 is an aluminium heat sink made for components in the TO-220 package, such as voltage regulators (7805, LM317), power MOSFETs (IRFZ44N) and power transistors (TIP120). It draws heat away from the component's metal tab and spreads it into the air, helping the part run cooler and handle more current without overheating.

Aluminum Heat SinkTO-220 Specifications

• Material: aluminium
• Fits: TO-220 package components
• Mounting: one screw through the hole in the TO-220 tab
• Thermal contact: use thermal paste or a thermal pad between tab and heat sink

Aluminum Heat SinkTO-220 Applications

• Cooling 7805, 7812 and LM317 voltage regulators
• MOSFETs and transistors in motor drivers and LED dimmers
• Output transistors in small audio amplifiers
• Linear power supplies and battery chargers
• Repairing and upgrading power boards

What's in the Box

• 1 × aluminium heat sink for TO-220

Tip: The metal tab of a TO-220 part is connected to one of its pins (the drain on most MOSFETs, ground on a 7805), so use an insulating pad and washer if the heat sink touches other parts or carries more than one component. A thin layer of thermal paste greatly improves heat transfer.
