AI Overview
Aluminum Nitride (AlN) TO-220 substrates are high-performance ceramic insulating sheets, commonly used to electrically isolate power transistors, MOSFETs, and IGBTs from a heat sink while providing superior thermal conductivity. They offer 5–10 times higher thermal conductivity than standard alumina (Al₂O₃) ceramics, with excellent electrical insulation and a thermal expansion coefficient similar to silicon, making them ideal for high-power, high-temperature applications.

Why is aluminum nitride so expensive?
High-purity AlN powder with controlled particle size and low oxygen content is expensive. Sintering temperatures often exceed 1800 °C, requiring specialized equipment and controlled atmospheres (typically nitrogen or argon). Additional costs come from sintering aids, machining, and moisture protection.Sep 10, 2025
