onsemi MURS220/NRVUS220V/SURS8220 Power Rectifiers

onsemi MURS220, NRVUS220V, and SURS8220 Ultra-Fast Recovery Power Rectifiers are designed for high-speed switching applications where efficiency and thermal performance are critical. With fast recovery times and low forward voltage drops, these onsemi rectifiers are ideal for use in switch-mode power supplies (SMPS), DC-DC converters, and power factor correction circuits. Robust surge capability and compact packaging make the MURS220, NRVUS220V, and SURS8220 rectifiers well-suited for demanding environments such as industrial systems, lighting ballasts, and motor control designs. These devices help improve overall system efficiency while reducing heat generation in high-frequency power conversion applications.
