Ultrafast Recovery Diodes in DO-41 Package, 50V–800V VRM Range, 1A Continuous Forward Current, 35ns Recovery, Ideal for High-Frequency Rectification and Power Conversion.
This DO-41 ultrafast recovery diode series—covering models like MUR120, MUR140, MUR160, and SF11G through SF19G—is designed for compact power applications requiring fast switching and low forward voltage drop. With a typical reverse recovery time of 25–35ns, VF up to 1.85V, and surge current capabilities up to 35A, these diodes support up to 1A continuous current. Ideal for high-speed rectification, snubber circuits, freewheeling and reverse-polarity protection in lighting, motor drives, and industrial converters.
