FAQ
Depending on the application, the GCM650M12K can improve system efficiency by 2-4% compared to equivalent silicon IGBT solutions. In high-frequency applications, the improvement can be even more significant due to the dramatically reduced switching losses.
The module requires a gate drive voltage of +18V/-4V for optimal performance. The negative gate voltage is kept relatively low to minimize turn-off losses while still providing adequate noise immunity. Gate resistance should be between 1Ω and 3Ω for most applications.
The GCM650M12K features an advanced thermal design with a junction-to-case thermal resistance of just 0.12°C/W. This is significantly better than many competing modules, allowing for higher power density and more compact system designs.
