577500B00000G Description

Short technical summary and product information.

This heat sink is designed for cooling TO-126 semiconductor packages in board-level vertical mounting applications. The part number 577500B00000G from Aavid, Thermal Division of Boyd Corporation features a rectangular finned shape made from aluminum with a black anodized finish for improved thermal emission.

Thermal performance is specified at 26.00°C/W under natural convection and 12.00°C/W with forced airflow at 300 LFM. It is rated for 1.0W power dissipation with a 30°C temperature rise. The heat sink attaches via press fit or slide-on method, providing a secure mechanical connection.

The dimensions are 19.81mm (0.780") width, 13.20mm (0.520") length, and 8.13mm (0.320") fin height. This compact profile makes it suitable for space-constrained PCB layouts where efficient thermal management of TO-126 devices is required.
