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 up to 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. 175 °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
