Frequently Asked Questions

Why R_θJC + R_θCS + R_θSA?
Heat flows in series: junction → case → heatsink → ambient. Each interface has thermal resistance. Total R_θJA = sum. T_J = T_A + (P × R_θJA).
How to choose heatsink R_θSA?
Required R_θSA = (T_Jmax - T_A)/P - R_θJC - R_θCS. Below required = OK. Smaller R_θSA = larger/finned heatsink. Add safety margin (T_Jmax - 25°C).
Thermal interface material?
Thermal grease ~0.5°C/W contribution. Thermal pad ~1-2°C/W. Hayır interface = 5-10°C/W (terrible). For high-power: phase-change pad or grease + good clamping.
