en.Wedoany.com Reported - Vishay Intertechnology has introduced 16 FRED Pt ultrafast rectifiers in the DFN6546A package, further enriching its power semiconductor portfolio. Designed for efficient, space-constrained applications in commercial, industrial, and automotive sectors, these devices offer a rated voltage of 200V and a current range from 6A to 15A, available in both commercial and AEC-Q101-certified automotive-grade versions.
The DFN6546A package, part of the Vishay Power DFN series, measures only 6.5mm × 4.6mm with a height of 0.88mm, contributing to improved power density and PCB utilization. Compared to similar-sized SMPC packages, the new devices achieve an approximately 10% reduction in height and up to a 50% increase in current capability. Through optimized copper mass and advanced chip attachment technology, thermal performance is enhanced, ensuring reliable operation at higher currents.
These ultrafast rectifiers are suitable for high-frequency and power conversion applications, including DC/DC converters, inverters, freewheeling diodes, snubber circuits, as well as reverse polarity and load dump protection. In the automotive sector, the ultrafast rectifiers can be used in engine control units, LED lighting, ADAS, LiDAR, camera modules, and 48V power architectures.
In terms of electrical performance, the forward voltage drop is approximately 0.75V, with low reverse leakage current and fast reverse recovery time, helping to reduce switching losses and improve system efficiency. The devices operate over a temperature range of -55°C to +175°C, suitable for harsh environments.
The DFN6546A package features wettable flanks, enabling automatic optical inspection without the need for X-rays. The devices comply with J-STD-020 MSL 1 requirements, with a maximum reflow temperature of 260°C, and are RoHS compliant, halogen-free, with matte tin-plated leads. Samples and production quantities of the new rectifiers are available now, with a lead time of approximately eight weeks.
