Vishay Intertechnology introduced five new series of 60 V, 100 V, and 150 V surface-mount Trench MOS Barrier Schottky (TMBS®) rectifiers in the low profile DFN3820A package with wettable flanks. Providing space-saving, high efficiency solutions for commercial, industrial, energy, and automotive applications, the VxNL63, VxNM63, VxN103, VxNM103, and VxNM153 each offer best in class current ratings up to 7 A, current density 50 % higher than the conventional SMA (DO-214AC) package, 12 % higher compared to the SMF (DO-219AB), and are available in Automotive Grade, AEC-Q101 qualified versions.

The first package in Vishay’s new Power DFN family, the DFN3820A features a compact 3.8 mm by 2.0 mm footprint and an extremely low typical height of 0.88 mm, allowing the Vishay General Semiconductor rectifiers released today to make more efficient use of PCB space. Compared to the conventional SMB (DO-214AA), conventional SMA (DO-0214AC and SOD128, the package’s size is 60 % 44 %, 35 % smaller, respectively. At the same time, the devices’ optimized copper mass design and advanced die placement technology allow for superior thermal performance that enables operation at higher current ratings. The rectifiers offer equivalent or higher current ratings to devices in the SMA (DO-214AC), SMB (DO-214AA), and SOD128 packages.
