Process Technology
Silicon carbide has a critical field roughly ten times that of silicon, so the drift layer can be far thinner for the same blocking voltage. The result is a much lower specific on-resistance at 1200 V and above, and a breakdown voltage that barely moves with temperature. The trade-offs are a narrower gate window and a body diode that should not carry continuous third-quadrant current.
Applications
High-voltage offline supplies, active clamp topologies, and single-stage PFC.
Selection Notes
- Silicon carbide holds a much flatter Rds(on) over temperature than silicon, but the gate window is narrow. Drive at 15–18 V on and a negative or zero volt off bias as the datasheet specifies.
- The body diode is not intended for continuous third-quadrant conduction. Where the topology requires it, check the datasheet's reverse conduction figures or add an external Schottky.
- Switching speed is limited by the gate loop, not the die. Keep the gate loop inductance low and budget for a negative turn-off spike on the gate.
- Paralleling needs matched VGS(th). Because VGS(th) spread is narrow the parts parallel well, but layout symmetry still decides current sharing.
Common Questions
Is the CRXF600M075G3 an N-channel or P-channel device?
It is N-channel. The drain-source rating is 750 V.
Can the CRXF600M075G3 be driven at 4.5 V?
No 4.5 V on-resistance figure is published for this part. It is characterised at 15 V gate drive, so use a driver that reaches 15 V.
How much gate charge does the CRXF600M075G3 need?
Qg is 10.9 nC. Size the driver against that figure at your switching frequency, and add the gate loop loss to the total dissipation budget.
What package does the CRXF600M075G3 come in?
TO-220F. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.
