4. Heatsink Definition
Selecting the ideal power semiconductor also requires considering realistic cooling conditions. Since heatsink properties vary based on the number, size, and arrangement of power modules, SemiSel simplifies this process by recommending a typical thermal impedance for air- or liquid-cooled systems. You can also input the thermal impedance of your custom heatsink, which will be factored into the calculations. For products like SKiiP or Stacks, that come assembled on a heatsink, pre-defined heatsinks are available, ensuring accurate thermal assessments.
- Freely defined cooling conditions with proposals for air or liquid cooled heatsinks
- Adapt heatsink dimensions and volume of air or liquid
- Select pre-defined heatsinks for SKiiP and other semiconductors
