SiC MOSFET
Evaluation Board
TO-247-4L Half-Bridge Evaluation Board
Operation Manual
For SiC MOSFET evaluation we are working with fast voltage and current slew rates, thus an appropriate evaluation environment is required.
Unfortunately, it is almost impossible to get an evaluation board which fulfills all the required conditions when considering
a device’s new package.
Therefore, we have developed an evaluation board based on the most common circuit configuration known as a half-bridge circuit. In order to
obtain appropriate evaluation conditions with simple preparation, this board is equipped with a driver circuit, an isolated power supply for the driver
circuit, an over current protection circuit, Gate signal protection circuit and so forth.
In this application note the evaluation board operational guide for the TO-247-4L package will be explained. Additionally the detail information
regarding topology, BOM, PCB layout, and electrical characteristics is described in the other application note. (TO-247-4L Half-bridge Evaluation
