Description

HEXFREDTM diodes of the S1242 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 snubber in
most applications. These devices of the S1242 are ideally suited for power converters, motors drives and other applications where
switching losses are significant portion of the total losses.
