Boyd TO220 Aluminium Heat Sink, 30°C/W

The Boyd TV58 is a compact, board-level aluminium heat sink engineered for efficient thermal management in electronic assemblies. Its distinctive channel-style design features slanted fins, which help to optimise airflow and increase the surface area for better heat dissipation. Finished with a durable black anodised coating, it not only provides a sleek, professional appearance but also offers enhanced corrosion resistance for long-term reliability in various environments.

This versatile heat sink is specifically designed to accommodate TO-220 and TO-220-single gauge semiconductor packages, making it a critical component for stabilising the temperature of power transistors, voltage regulators, and other heat-generating devices. A key feature is its flexible vertical or horizontal mounting orientation, allowing for easy integration into diverse PCB layouts and tight spaces where cooling is essential.

Performance and Construction

With a thermal resistance rating of 30°C/W, the TV58 effectively transfers heat away from sensitive components, helping to prevent overheating and ensure optimal circuit performance and longevity. Constructed from high-grade aluminium, it provides an excellent balance of lightweight construction and high thermal conductivity.

Applications

Its robust design makes it suitable for a wide range of applications, from industrial control systems and power supplies to consumer electronics, where consistent thermal performance is crucial. The compact dimensions allow it to be used in space-constrained designs without compromising on cooling efficiency.
