This aluminum heatsink is designed for all integrated circuits using the TO-220 package. These are compatible with all of our basic linear voltage regulators, MOSFETS, and the TIP120 / TIP31C / TIP32C Darlington transistors. The heatsink is capable of dissipating 3W @ 80°C and bolts directly to the back of the ICs; it should help keep them cool (or at least not as hot!).

Please Note: Hardware and transistor sold separately. We recommend a 4/40 x 1/4″ screw and a 4/40 nut to hold the heatsink in place.



  • Dissipate up to 3W @ 80°C
  • Dimensions: 0.75 x 0.52″
  • Bolts directly to most TO-220 ICs
  • Material: Aluminum
