FRED Pt® Ultrafast Rectifiers in DFN6546A Package

Vishay Semiconductor Diodes introduces 16 FRED Pt ultrafast rectifiers in a low-profile DFN6546A package with wettable flanks. Providing space-saving, high-efficiency solutions for commercial, industrial, and automotive applications, the 200 V devices provide current ratings from 6 A to 15 A and are available in commercial- and automotive-grade, AEC-Q101 qualified versions. The DFN6546A package features a compact 6.5 mm x 4.6 mm footprint and an extremely low typical height of 0.88 mm, allowing the Vishay Semiconductors rectifiers to make more efficient use of PCB space. At the same time, the optimized copper mass design and advanced die placement technology allow for superior thermal performance that enables operation at higher current ratings. Compared to 200 V components in the SMPC (TO-277A) package with the same footprint, the rectifiers offer a 10% lower profile and a 50% higher current rating. The single and dual devices offer low reverse leakage current and operate over a wide temperature range from -55°C to +175°C, while their low forward voltage drop of 0.75 V, combined with a fast reverse recovery time (t_rr) and low reverse recovery charge (Q_rr), reduces power losses to improve efficiency. The wettable flanks of their DFN6546A package allow for automatic optical inspection (AOI), eliminating the need for an X-ray inspection. Ideal for automated placement, the rectifiers offer an MSL moisture sensitivity level of 1, per J-STD-020, and a LF maximum peak of +260°C. The components are RoHS compliant and halogen-free, and their matte tin-plated leads meet the JESD 201 Class 2 whisker test.
