Industrial Electronics: The Dual Heat and EMI Challenge with GaN and SiC Semiconductors

Application of Laird CoolZorb hybrid thermal and EMI absorbing material on GaN and SiC industrial power components.
Energy efficiency and power density are the key pillars of modern industrial electronics. The widespread adoption of power semiconductors based on GaN (Gallium Nitride) and SiC (Silicon Carbide) has revolutionized the design of industrial power supplies and converters, enabling ultra-high switching frequencies within smaller footprints. However, this evolution has intensified thermal management and electromagnetic compatibility (EMC) challenges, concentrating intense heat and high-frequency noise within the same confined PCB spaces.

The Effectiveness of Hybrid Materials: The CoolZorb™ Series

Resolving thermal and EMI issues separately in modern industrial layouts is often unfeasible due to space constraints. The ideal strategy involves utilizing multi-functional hybrid absorbers capable of tackling both challenges simultaneously. CoolZorb™ materials provide unique engineering advantages:

  • Dual Functionality: They function concurrently as a traditional thermal gap filler and a high-frequency electromagnetic interference (EMI) absorber.
  • Targeted Noise Suppression: Specifically engineered to attenuate radiated emissions and cross-talk within cavities containing fast-switching power semiconductors.
  • Design Optimization: By eliminating the need for two separate components (a thermal pad and an absorber), they reduce overall device thickness, weight, and assembly costs.
