Vishay Intertechnology has launched a new family of 16 FRED Pt ultrafast rectifiers in the DFN6546A package, targeting space-constrained, high-efficiency applications across automotive, industrial, and consumer markets.
The new 200 V devices offer current ratings from 6 A to 15 A and are available in both commercial and AEC-Q101 qualified automotive-grade versions. The DFN6546A package features a compact 6.5 mm × 4.6 mm footprint with an ultra-low height of 0.88 mm, enabling improved PCB space utilization and supporting increasingly dense power designs.
From a performance standpoint, the rectifiers deliver low forward voltage (approximately 0.75 V), fast reverse recovery, and low reverse recovery charge, reducing switching losses and improving overall system efficiency. Enhanced thermal performance is achieved through optimized copper mass and die placement, allowing higher current capability compared to similarly sized packages.
The devices are designed for a wide range of applications, including DC/DC converters, high-frequency inverters, freewheeling diodes, and protection circuits. In automotive systems, they target use cases such as ECUs, ADAS, lighting, and 48 V power architectures in EVs and HEVs. They also support industrial automation, telecom, and consumer electronics applications.
A key packaging advantage is the inclusion of wettable flanks, enabling automated optical inspection (AOI) and eliminating the need for X-ray inspection—an important factor for high-volume manufacturing efficiency.
From a market perspective, this release highlights the continued evolution of silicon-based rectifiers through packaging and thermal innovation. While wide-bandgap devices are gaining share in high-voltage segments, optimized silicon rectifiers remain highly relevant in cost-sensitive, high-volume applications where efficiency, reliability, and compact form factors are critical.
Vishay’s latest offering reinforces its position in discrete power components by addressing the growing demand for miniaturization and improved thermal performance in modern power electronics systems.
