The device supports a continuous drain current of 63 A and a pulsed current of 223 A, with power dissipation rated at 294 W. Operating junction temperature ranges from -55°C to +175°C. Key electrical parameters include a gate threshold voltage of 2.7 V typical, total gate charge of 91 nC, and reverse recovery charge of 322 nC.
Verify the specific ordering suffix J2 corresponds to the TO-263-7XL package variant. Confirm compliance requirements such as RoHS and REACH status directly with the manufacturer or authorized distributors. Ensure thermal management designs account for the specified junction-to-case thermal resistance and derating curves provided in the datasheet.
Select this component for high-efficiency power conversion applications requiring robust switching performance. The separate Kelvin source pin aids in minimizing gate ringing and improving switching speed. Consider the thermal resistance and safe operating area when designing for high-current or high-temperature environments.
This part belongs to Wolfspeed's third-generation silicon carbide MOSFET portfolio. It utilizes advanced SiC technology to achieve superior performance compared to traditional silicon devices. The TO-263-7XL package provides enhanced thermal dissipation capabilities suitable for compact power electronics designs.
Direct replacements should be sought within the Wolfspeed C3M0040120 series or comparable third-generation SiC MOSFETs with similar voltage, current, and package specifications. Verify pinout compatibility, especially regarding the separate driver source pin configuration.
