Datasheet

MBR Series Schottky Barrier Rectifiers, the latest Littelfuse devices based on silicon Schottky diode technology, are available at Rutronik. The two new series are designed to meet the general requirements of commercial and industrial applications. These Schottky Barrier Rectifiers come with extremely fast switching speed, very low forward voltage drop, low leakage and high junction temperature capability.

The DUR Series Ultrafast Rectifier has ultrafast switching speed with very low reverse recovery time (T_RR), high blocking voltage of up to 1200V and low leakage.

Thanks to its low forward voltage drop, it is possible to minimise power loss and increase efficiency during converter operation.

Their higher temperature capability and low leakage provide higher reliability in harsh, high temperature environments and applications with minimal cooling availability.

Typical applications for both series include uninterruptible power supplies, high frequency switch-mode power supplies and DC-DC converters, as well as free-wheeling diodes and polarity protection diodes.

The DUR Series Ultrafast Rectifier also addresses applications such as anti-parallel diodes for high frequency switching devices, e.g. IGBTs, inductive heating and melting as well as ultrasonic cleaners and welders.
