Aavid Black Anodized Aluminum TO-220 Heat Sink Fin PCB Mount Pin Style

Aavid Black Anodized Aluminum TO-220 Heat Sink Fin PCB Mount Pin Style

This is a black anodized aluminum fin heat sink from Aavid designed for TO-220 package components. It features a longitudinal fin array for passive convection cooling and mounts directly to a PCB via two through-hole pins. Two mounting holes on the body allow optional mechanical fastening to the component or board. The black anodized finish improves thermal emissivity compared to bare aluminum.

Applications

TO-220 heat sinks like this are standard components in electronics design, used to dissipate heat from TO-220 package devices such as voltage regulators (e.g. 7805, LM317), power transistors, MOSFETs, and thyristors. The PCB pin mount style makes them well suited for through-hole assembly on circuit boards where space is limited and a clip or screw mount is impractical. Aavid (now part of Boyd Corporation) has been a leading manufacturer of thermal management components for decades, and their TO-220 heat sinks are widely used in power supply design, motor drivers, audio amplifiers, and industrial control electronics. The black anodized finish is standard on Aavid's higher-emissivity heat sinks intended for passive convection environments.
