The increasingly complex network of electricity generators and consumers poses major challenges for Austria's energy transmission infrastructure. For example, the use of increasingly powerful inverters and rectifiers in the transmission grid results in unwanted currents with very low frequencies. These are known as quasi-direct currents and cause problems in the power grid.

Vishay Intertechnology (VSH) introduced four new series of surface-mount standard rectifiers in the low profile DFN6546A Power DFN package with wettable flanks.The 5 A SE50N6x, 8 A SE80N6x, 10 A SE100N6x, and 12 A SE120N6x families support reverse voltages of 200 V, 400 V, and 600 V, and are offered in AEC‑Q101 qualified versions for automotive use. The DFN6546A package measures 6.5 mm x 4.6 mm with a typical height of 0.88 mm, enabling more efficient PCB use and AOI thanks to wettable flanks. Compared with SMPC (TO‑277A) devices of the same footprint, these rectifiers provide a 10 % lower profile, 20 % higher current ratings, and 82 % higher forward surge capability. Forward voltage drops are as low as 0.77 V, with operation from -55 °C to +175 °C. Samples and production quantities are available with eight-week lead times.

Coordinating existing rectifier taps cut green-hydrogen harmonics 48%, raised profit 31%, and made pricey 24-pulse upgrades unnecessary — a 37.5% cost cut.

Power supplies combine transformers, rectifiers, capacitors, and voltage regulation to convert household electricity into the stable power required by modern electronic circuits.
