Precision ceramic components for power electronics

Why Are Technical Ceramics Used in Power Electronics?

Technical ceramics are used in power electronics for electrical insulation, thermal transfer, and dimensional stability in power modules and converters. Aluminum nitride (AlN) substrates provide thermal conductivity of 170-190 W/m·K while maintaining dielectric isolation (>10¹⁴ Ω·cm), enabling efficient heat dissipation from IGBT and MOSFET devices. Alumina (Al₂O₃) offers cost-effective electrical insulation with moderate thermal performance for power module housings and bushings. Silicon nitride (Si₃N₄) delivers thermal shock resistance for demanding applications exposed to rapid temperature cycling. Precision machining to ±0.003 mm ensures proper fit in power assemblies, while metallization-ready surfaces (Ra 0.05 μm) support direct bonded copper (DBC) assembly for reliable thermal interfaces.
