Ultra-Fast Soft Recovery Diode Module
Description
Ultra-FRD module devices are optimized to reduce losses
and EMI/RFI in high frequency power conditioning electrical systems.
These diode modules are ideally suited for power converters,
motors drives and other applications where switching losses
are significant portion of the total losses.
Features
☞ Repetitive Reverse Voltage : VRRM = 400V
☞ Low Forward Voltage Drop : VF(typ.) = 1.2V
☞ Average Forward Current : IF(AV.) = 300A @ Tc = 100℃
☞ Ultra-Fast Reverse Recovery Time : trr(typ.) = 125 ns
☞ Extensive Characterization of Recovery Parameters
☞ Reduced EMI and RFI
☞ Isolation Type Package
Applications
Motor Drives, Free wheel use, High Power Converters, Welders,
Various Switching and Telecommunication Power Supply.
