Tailor-made superjunction MOSFET perform in automotive designs

May 1, 2020  Stephen Law

INFINEON TECHNOLOGIES CoolMOS CFD7A series silicon-based, high-performance tailor-made superjunction MOSFET can be used in both the PFC and the dc-dc stage of on-board charger systems and HV-LV dc-dc converters specifically optimized for electric-vehicle applications. Device is fully compatible with system voltages up to 475 VDC. Higher efficiency levels are made possible by the Kelvin-source concept reaching peak efficiency levels up to 98.4% measured. Thanks to their intrinsic fast body diode and the broad portfolio line-up in TO and SMD packages, devices are suitable for PFC and dc-dc stages. The product family allows reaching higher switching frequencies with low gate losses enabling more power-dense hence more compact designs.
