TO-220 Clip-On Heatsink

Get the most out of your regulators, transistors, and other TO-220 packaged chips by clipping on this easy-to-use heat sink. This basic ~25°C/W heatsink allows you to dissipate about 3 Watts of power through a TO-220 package (assuming an ambient temperature of 25°C and max die temperature of 85°C) without the need for screws or thermal paste.

Most TO-220 devices can dissipate about 2 Watts without a heatsink, so using this clip-on heatsink significantly improves thermal performance, ensuring stable operation even with higher power loads.

Features include:

• Simple clip-on design, no screws or thermal paste required
• Compact size: 19mm x 13mm x 13mm (0.7" x 0.5" x 0.5")
• Weight: 1.88g
• Thermal resistance approximately 25°C/W
• RoHS compliant

Note: As of July 2, 2020, this product uses a new design that is more compact but has slightly higher thermal resistance compared to the previous version.
