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 approximately 1W and bolts directly to the back of the ICs; it should help keep them cool (or at least not as hot!). Hardware sold separately – a 4/40 x 1/4″ screw and a 4/40 nut work well.
