Buck Boost Evaluation Board for 650 V Silicon Carbide C3M™ MOSFET in a TO-247-X Package
KIT-CRD-3DD065P
Note Last Time Buy. Recommended replacement:SpeedVal Kit
This evaluation board demonstrates the switching and thermal performance of 650 V 60 mΩ Silicon Carbide (SiC) C3M™ MOSFET in a TO-247-4 package configured in a half bridge topology. The board is designed for characterizing EON and EOFF losses and steady state thermal performance in Silicon Carbide MOSFETs. The board can be configured to run as a buck or boost converter in either synchronous or asynchronous modes. The PCB also supports replacing the SiC MOSFETs with TO-247-3 package components to allow for evaluation of either package. A full LTSpice model including parasitic elements that nearly matches the performance of the hardware is available for download.
This design allows measurement of:
- Timing (TDelay-On; TDelay-Off; TRise; TFall)
- Overshoot (VDS-Max; ID-Max)
- Speed (di/dt; dv/dt)
- Switching Loss (EON; EOFF; ERR)
- Efficiency during operation up to 2.5kW
Specifications
- Max DC Input / Output Voltage of 450V
- Max Power of 2.5kW @ 100kHz (limited by on-board inductor; higher levels possible with alternate inductor)
- Compatible with TO-247-4 and TO-247-3 SiC MOSFETs;
- Compatible with TO-247 and TO-220 SiC Schottky diodes
- Dedicated gate drivers and isolated power supplies for each C3M SiC MOSFET
- Optimized locations for scope probe measurements of drain current; VGS; and VDS and IS
- Synchronous and asynchronous buck and boost topologies supported
- Kit includes two SMA to BNC adapters for measuring VGS waveforms
- Includes heatsink; thermal clips and isolated thermal pads

How Wolfspeed’s Fayetteville Team Turns Silicon Carbide Expertise into Customer Momentum
At our Fayetteville site, Ty McNutt and his team don’t just solve for specs —they rethink systems. That’s the difference between supplying parts and becoming the partner customers rely on.
