Diamond Heat Spreaders

Category: Thermal Solutions

Ultra-high thermal conductivity single crystal and polycrystalline diamond substrates for thermal management in high-power electronics and laser systems.

Appsilon diamond heat spreaders provide thermal conductivity up to 2200 W/mK — over 5x better than copper. Designed for GaN-on-diamond, high-power laser diodes, and advanced packaging applications where thermal performance is critical.
