Product Overview
The KMBF series by Fuxinsemi are 1.0A Surface Mount Schottky Barrier Single-Phase Bridge Rectifiers designed for efficient power conversion. These rectifiers offer surge overload ratings up to 30 amperes peak and are ideal for automated replacement in space-constrained applications. Their low-profile mini-dip bridge package saves valuable board space. Constructed with reliable, low-cost molded plastic technology and featuring silicon epitaxial chips with metal silicon junctions, these lead-free parts meet RoHS requirements. They are suitable for various applications requiring single-phase half-wave rectification.
