The rapid growth of AI infrastructure is increasing demand for compact and efficient server power systems. In high-density power architectures, both device performance and package structure play important roles in achieving stable switching behavior and effective PCB space utilization.

This whitepaper discusses the role of 600V Super Junction MOSFETs in major server power topologies and examines the switching characteristics and PCB space advantages of TOLL packaging compared with TO-263-7P. It also reviews the impact of the Kelvin Source structure on switching stability in high-density power designs.
