What Can SuperQ™ Do for Class-D Audio Amplifiers
Modern Class-D audio amplifiers are being pushed to deliver higher output power, better efficiency, lower distortion, and smaller form factors, all while managing strict thermal and EMI constraints.
Whether you’re designing high-power professional audio systems, automotive amplifiers, or compact consumer audio products, switching performance directly impacts sound quality, efficiency, and thermal management.
SuperQ MOSFETs reduce switching losses, support higher voltages (150V – 300V), lower FET count, enabling higher power density.

SuperQ MOSFETs are optimized for high-efficiency Class-D topologies, enabling superior performance in applications ranging from professional audio amplifiers to automotive and consumer systems.
Why SuperQ?
SuperQ MOSFETs reduce both conduction and switching losses, enabling higher efficiency, lower distortion, and cooler operation.
SuperQ = Lower Loss + Cleaner Switching ➔ Better Audio Performance
- Higher efficiency at high output power
- Reduced thermal stress ➔ smaller, quieter systems
- Lower switching losses ➔ improved linearity and THD performance
- Higher switching frequency capability ➔ smaller passive components
- Best-in-class cost-to-performance ratio
