HEXFRED®
Ultrafast Soft Recovery Diode, 240 A
FEATURES
Lug terminalanode 1Lug terminalanode 2•Very low Qrr and trr•Lead (Pb)-free
•Designed and qualified for industrial level
RoHSCOMPLIANTBENEFITS
•Reduced RFI and EMI•Reduced snubbing
TO-244Base commoncathodeDESCRIPTION
HEXFRED® diodes are optimized to reduce losses andEMI/RFI in high frequency power conditioning systems. Anextensive characterization of the recovery behavior fordifferent values of current, temperature and dI/dt simplifiesthe calculations of losses in the operating conditions. Thesoftness of the recovery eliminates the need for a snubber inmost applications. These devices are ideally suited forpower converters, motors drives and other applicationswhere switching losses are significant portion of the totallosses.
