Vishay’s new 200 V FRED Pt automotive-grade rectifiers deliver up to 15 A in new 0.88 mm DFN package

Vishay Intertechnology has launched a new range of 16 FRED Pt ultrafast rectifiers housed in the compact DFN6546A package, designed for automotive and industrial applications. These rectifiers offer voltage ratings of 200 V and continuous current capacities ranging from 6 A to 15 A in single configurations, with dual options delivering up to 2×7.5 A. The DFN6546A package measures 6.5 by 4.6 mm with a low profile of just 0.88 mm, providing a significant reduction in height compared to Vishay’s previous SMPC (TO-277A) package while supporting 50% higher current ratings. The new package incorporates wettable flanks, enabling automated optical inspection (AOI) and removing the need for X-ray inspection during manufacturing, which can streamline quality control processes. Electrical characteristics are consistent across the product family, featuring a forward voltage drop of 0.75 V at rated current, an operating temperature range from −55 to +175 °C, and a maximum junction temperature of 175 °C. The FRED Pt series is distinguished by its fast reverse recovery time and low reverse recovery charge, key factors that minimise switching losses in inverter and converter circuits. Vishay is targeting these rectifiers primarily at electric vehicle (EV) and hybrid electric vehicle (HEV) applications, including 48 V boardnets, onboard chargers, and battery management systems. Additional automotive uses include electronic control units (ECUs), advanced driver-assistance systems (ADAS), lidar, and camera modules. Beyond automotive, the devices are suitable for general-purpose roles such as high-frequency inverters, DC/DC converters, freewheeling diodes, load dump protection, and snubber circuits. Manufactured to meet stringent automotive standards, all versions of the rectifiers are available in both commercial and AEC-Q101 automotive-grade variants. The devices comply with RoHS regulations, are halogen-free, and feature matte tin leads that pass industry-standard whisker testing. Vishay has confirmed that samples and production quantities are currently available, with an eight-week lead time, signalling readiness for immediate integration into next-generation electric and hybrid vehicle systems.
