Mini Heat Sink TO-220

Mini Heat Sink TO-220

The Mini heat sink TO-220 is a compact, efficient thermal management component designed to provide effective heat dissipation for TO-220 power semiconductors such as voltage regulators, MOSFETs, and power transistors. Made from black anodized aluminum, it offers excellent thermal conductivity and corrosion resistance in a lightweight profile.

With a thermal resistance typically around 25°C/W, this heat sink allows up to 3 W of heat dissipation in free air conditions, making it suitable for low to moderate power applications. Its compact footprint is ideal for space-constrained designs, including embedded systems, DC power supplies, and DIY electronics.

Available in both clip-on and bolt-on mounting styles, the mini heat sink TO-220 ensures reliable contact with the device for optimal thermal transfer. It is compatible with standard TO-220 packages such as the LM7805, IRF540N, or TIP122, and can be installed without thermal compound in many cases, simplifying assembly.
