The FGD3040G2-SN00401V is a silicon carbide (SiC) MOSFET belonging to the FGD3040G2 series. It features a 650 V drain-source voltage rating and a 30 A continuous drain current at 25 °C. The device utilizes an N-channel enhancement mode structure with a TO-263AB surface-mount package. Key electrical characteristics include a maximum on-resistance of 78 mΩ at 10 V gate drive and a typical threshold voltage range of 2.5 V to 3.5 V. The component supports high-frequency switching applications due to its low gate charge and fast reverse recovery behavior inherent to SiC technology.
Verify the specific suffix SN00401V against official datasheets to confirm tape-and-reel packaging specifications and lot traceability. Ensure the ordering part number matches the exact pinout and marking requirements for your PCB design. Cross-reference with authorized distributors to confirm authenticity and avoid counterfeit components.
Select this component when designing systems requiring high efficiency at elevated temperatures or frequencies. Evaluate the thermal management requirements based on the junction-to-case thermal resistance. Compare the total power loss, including switching and conduction components, against alternative silicon IGBTs or MOSFETs to validate cost-performance benefits.
This part belongs to the FGD3040G2 family of SiC MOSFETs from onsemi. The family shares common die technology but may vary in packaging or specific electrical tolerances. The FGD3040G2 series is engineered for automotive and industrial power electronics demanding robust performance under harsh operating conditions.
Direct replacements must match the 650 V / 30 A rating and TO-263AB package. Verify that substitute parts have compatible gate threshold voltages and on-resistance values to ensure circuit stability without redesigning the gate drive network.
