)ƒ = 270A/µs • Reduced RFI and EMI • Reduced Snubbing • Extensive Characterization of Recovery Parameters Anode 1 AC Cathode 2 Isolated Base Description HEXFRED diodes are optimized to reduce losses and EMI/RFI in high frequency power conditioning systems.
An extensive characterization of the recovery behavior for different values of current, temperature and di/dt simplifies the calculations of losses in the operating conditions.
The softness of the recovery eliminates the need for a snu...
