Charged EVs | 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 introduced 16 FRED Pt ultrafast rectifiers in a new DFN6546A package, covering 200 V ratings and continuous current from 6 A to 15 A in single configurations and 2×3 A to 2×7.5 A in dual configurations. All 16 are available in both commercial and AEC-Q101 automotive-grade versions.
The DFN6546A measures 6.5×4.6 mm with a typical profile of 0.88 mm. Compared to Vishay’s SMPC (TO-277A) package at the same footprint, the new package cuts height by 10% and supports 50% higher current ratings. Wettable flanks allow automated optical inspection (AOI), eliminating the need for X-ray inspection.
Key electrical specs are uniform across the family: 0.75 V forward voltage drop at rated current, operating range of −55 to +175 °C and 175 °C maximum junction temperature. Fast reverse recovery time (trr) and low reverse recovery charge (Qrr) are the defining characteristics of the FRED Pt line—the parameters that determine switching losses in inverter and converter applications.
Vishay targets the parts at 48 V boardnets, onboard chargers and battery management systems in EVs and HEVs, along with ECUs, ADAS, lidar and camera systems. General-purpose targets include high-frequency inverters, DC/DC converters, freewheeling diodes, load dump protection and snubbers.
Devices are MSL 1 per J-STD-020, rated to a 260 °C LF peak, RoHS-compliant and halogen-free, with matte tin leads passing JESD 201 class 2 whisker testing. Samples and production quantities are available now with 8-week lead times.
