Key Features
- Black anodized extruded aluminum construction at 38.1 mm height delivers enhanced thermal emissivity and corrosion resistance for long-life heat dissipation in power electronics
- Radial fin geometry maximizes surface area for convective cooling, supporting thermal resistance values suitable for TO-220, TO-247, and similar power packages up to several tens of watts
- Drop-in mounting compatibility with standard power semiconductor footprints allows tool-free integration into motor drive, inverter, and linear regulator PCB designs
Applications
The 533402B02552G is used to cool high-power semiconductor devices such as power MOSFETs, IGBTs, and linear regulators in motor drives, switching power supplies, and industrial inverter designs where junction temperatures must stay below 150°C. Its 38.1 mm extruded radial-fin body provides sufficient thermal mass and surface area for dissipating tens of watts with modest forced-air cooling. The anodized black finish improves infrared emissivity, making it effective even in natural convection environments with limited airflow.

Frequently Asked Questions
What height and fin configuration does the 533402B02552G heat sink offer for cooling a TO-220 power MOSFET?
The 533402B02552G stands 38.1 mm tall with a radial extruded fin array in black anodized aluminum, providing a large cooling surface area suitable for dissipating 20 W to 40 W from a TO-220 power MOSFET depending on airflow velocity and mounting thermal interface material used.
How does the black anodized finish on the 533402B02552G improve thermal performance compared to a bare aluminum heat sink?
The black anodized finish raises the surface emissivity of the aluminum from approximately 0.05 for bare metal to about 0.85, increasing radiated heat transfer by over 10× in natural convection scenarios and allowing the heat sink to maintain device junction temperatures at least 5°C to 10°C lower than untreated aluminum under equivalent power dissipation conditions.
What is the typical lead time for the 533402B02552G and are shorter-lead-time alternatives available from Aavid?
The factory lead time for the 533402B02552G is 6 weeks from Aavid Thermalloy. Engineers with tighter schedules can evaluate stocked equivalent extruded heat sinks in the same 38 mm height class from distributor inventory, ensuring no disruption to production timelines while a long-term supply of the exact part is sourced.
