Additional Details

The C3M0021120K features a blocking voltage of 1200V and a typical on-resistance of 21 mΩ. The gate charge is typically low, reducing the power required to drive the MOSFET. The device is designed for operation at high temperatures, typically up to 150°C or higher. Proper heat sinking is essential to dissipate heat generated by the MOSFET. The package type is typically a TO-247 or similar high-power package. SiC MOSFETs have significantly lower switching losses compared to silicon MOSFETs, especially at high frequencies. The higher blocking voltage allows for higher bus voltages, reducing current requirements. The avalanche ruggedness provides added protection against voltage transients. This MOSFET is ideal for applications where efficiency, power density, and reliability are critical.
