Silicon Carbide MOSFETs in a TOLL package enable high power density designs due to their small footprint and low profile. The SpeedVal Kit TOLL power daughter cards feature two MOSFETs arranged in a half-bridge configuration. The unique card edge interface provides low inductance and simplifies the process of swapping out components, enabling high-quality measurements and quick comparisons between different devices. Power Daughter Cards are optimized for making accurate high-bandwidth current and voltage measurements.

An on-board current shunt can be optimized for highly accurate dynamic switching tests, or high-power thermal testing with the evaluation board. The coaxial MMCX connectors for VGS and IDS and BNC connectors for VDS provide noise-free measurements to improve accuracy and simplify gate drive optimization. ​

The power daughter cards include a pre-assembled heatsink which aligns with a fan on the motherboard to enable high-power testing.
