Schottky ultra-fast rectifiers switching designed for commercial and industrial applications

Available from Digi-Key, Littelfuse Schottky ultra-fast rectifiers DUR series provide ultra-fast switching speed. This series is designed to meet the general requirements of commercial and industrial applications. The series are popular with designers because of their ultra-fast switching speed with very low reverse recovery time (Trr), high blocking voltage (up to 1200V), low leakage, and low forward voltage drop. This makes it possible to minimise power loss and increase efficiency during converter operation. Their higher junction temperature capability and low leakage provide higher reliability in harsh, high temperature environments. They can be used in applications requiring uninterruptible power supplies, high frequency switch-mode power supplies, and DC-DC converters, and can also be used as anti-parallel diodes for high frequency switching devices such as IGBTs. Other applications include inductive heating/melting and ultrasonic cleaners and welders.
