Vishay's New 600-V, 8-A PFC Rectifier Series Features Diodes With Voltage Drop as Low as 1 V and Recovery Charge as Low as 62 nC in 175 °C-Rated Package

Addressing 70-W to 400-W switchmode power supply (SMPS) applications, the new rectifiers will provide an energy-efficient power factor correction (PFC) solution for laptop computer and printer adaptors, desktop PCs, TVs and monitors, game controllers, and ac-to-dc power supplies in DVD and Blu-ray players. The devices will also be used for lighting/ballast applications. Their low VF, optimal stored charge, and low recovery current are designed to minimize conduction and switching losses, improve application efficiency, and reduce EMI generation.



Three device versions are available to suit the main types of SMPS PFC implementations. Each is available in TO-220AC and TO 220FPAC packages with a 175 °C maximum junction temperature-rating.
