950V super-junction mosfets

PFD7 is a family of 950V super-junction mosfets from Infineon, that can achieve 450mΩ Rds(on) in DPAK or 60mΩ in TO247.

Gate-source threshold voltage is 3±0.5V.

“Due to the low threshold voltage and tolerance, linear mode operation is avoided while allowing lower driving voltage and reduced idle loss,” according to the company. “By integrating a fast body diode with low reverse recovery charge, they offer hard commutation ruggedness and reliability.”


It also said that gate charge is 60% better than its earlier 900V C3 mosfet family, contributing to up to 4K lower mosfet temperature and 0.2% improved PFC efficiency while matching LLC efficiency.
