MBR Schottky Barrier Rectifiers Littelfuse MBR Schottky Barrier Rectifiers (Standard Schottky) are designed for commercial and industrial applications and suitable for high-frequency switch-mode power supplies. The MBR provides super-fast switching speed, very low forward voltage drop, high temperature, and low leakage performance. The rectifiers offer high reliability in high ambient temperatures or applications with minimal cooling available. The MBR minimize power loss and have greater efficiency during converter operation with super-fast switching speed and a very low forward voltage. Littelfuse MBR Schottky Barrier Rectifiers provide higher reliability in harsh, high-temperature environments.
