IF(AV) Rectangular waveform VRRM range IFSM 5 �s sine 100Apk, TJ=125�C (per leg) range A V Description/ Features The 203DNQ Schottky rectifier doubler module series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation 175 �C junction temperature. Typical applications are in high current switching power supplies, plating power supplies, UPS systems, converters, free-wheeling diodes, welding, and reverse battery protection. �C TJ operation High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Modified JEDEC Outline TO-244AB Dimensions in millimeters and (inches)VR Max.
