Schottky Barrier Diodes

[NEW]200V Ultra-low IR Schottky Barrier Diodes RBxx8BM/NS200

 

The RBxx8BM/NS200 expands on the RBxx8 lineup of SBDs enabling high temperature operation that have already been proven in the automotive market in Japan. This new series offers ultra-low leakage current (IR) characteristics to achieve high withstand voltage of 200V. Replacing Fast Recovery Diodes (FRD) and rectifier diodes typically used in vehicle systems with ROHM's new SBDs make it possible to improve forward voltage (VF) characteristics significantly (11% lower than conventional FRDs). This reduces application power losses and allows smaller package designs by reducing heat generation, contributing to greater space savings.
