Additional Details

The KP200 typically has a drain-source voltage (VDS) rating of 650V to 800V, depending on the specific variant. Its on-resistance (RDS(on)) is a critical parameter, influencing the conduction losses. Avalanche energy rating (EAS) specifies its ability to withstand avalanche breakdown. The TO-220 package allows for efficient heat sinking, but proper thermal design is crucial to maintain the MOSFET within its safe operating area. Refer to the Infineon datasheet for detailed specifications, including gate charge, switching times, and thermal resistance values. These parameters are crucial for optimizing the performance and reliability of power electronic circuits.
