Vishay has released 16 single and dual FRED Pt ultrafast rectifiers in low-profile DFN6546A packages with wettable flanks. The 200-V devices occupy a 6.5×4.6-mm footprint with a typical height of 0.88 mm. Rated from 6 A to 15 A, they offer a 10% lower profile and 50% higher current than comparable 200-V SMPC (TO-227A) devices.
The rectifiers are designed for high-frequency power conversion and protection in automotive, industrial, and consumer systems, including EV powertrains, ADAS, industrial automation, and telecom equipment. Automotive variants are AEC-Q101 qualified.
For these applications, the rectifiers feature low reverse leakage current and operate over a wide temperature range from −55 °C to +175 °C. A low forward voltage drop of 0.75 V, combined with fast reverse recovery time and low reverse recovery charge, reduces power losses and improves efficiency.
The DFN6546A package’s wettable flanks enable automatic optical inspection (AOI), eliminating the need for X-ray inspection and supporting automated assembly. The devices are MSL 1 qualified per J-STD-020, with a maximum peak reflow temperature of 260 °C.
Samples and production quantities of the single and dual FRED Pt ultrafast rectifiers are available now, with lead times of eight weeks.
