AI Overview
Aluminum Nitride (AlN) sheets are high-performance ceramic substrates essential for high-power, high-voltage IGBT modules in 2026, offering thermal conductivity (170–230 W/m·K) 5–10 times higher than traditional alumina (
). They enable efficient heat dissipation, allowing for higher power densities, improved reliability, and increased current-carrying capacity in electric vehicles, wind power, and industrial inverters.
Key Properties for IGBT Applications (2026)
- High Thermal Conductivity: Typically $\ge$170 W/m·K, with specialized sheets reaching >200 W/m·K.
- Thermal Expansion Match: The CTE (3.5 - 4.6 x /K) is closely matched to silicon and SiC, reducing thermal fatigue in IGBTs.
- Electrical Insulation: High dielectric strength (14-15 kV/mm) and low dielectric loss, ensuring safety in high-voltage environments.
- Superior Reliability: AlN-based power modules show more than twice the lifespan of -based modules.
