Vishay Intertechnology has introduced four new series of surface-mount standard rectifiers in the low-profile DFN6546A package with wettable flanks. Providing space-saving solutions for power line polarity protection and rail to rail protection in commercial, industrial, and automotive applications, the 5 A SE50N6x, 8 A SE80N6x, 10 A SE100N6x, and 12 A SE120N6x are each available with reverse voltages of 200V, 400V and 600V, and are offered in AEC-Q101 qualified versions.

Featuring an oxide planar chip junction design, the rectifiers offer typical reverse leakage current less than 0.1μA, while their low forward voltage drops down to 0.77V reduces power losses to improve efficiency. The devices operate over a wide temperature range from -55 °C to +175°C, and provide ESD capability in compliance with IEC 61000-4-2, air discharge mode. 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, LF maximum peak of 260 °C. The devices are RoHS-compliant and halogen-free.

The latest package in Vishay’s new Power DFN family, the DFN6546A features a compact 6.5 mm by 4.6 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. At the same time, the devices’ advanced construction and die placement technology allow for a higher copper content and larger chip sizes, resulting in improved thermal performance, higher current ratings, and forward surge current capability. Compared to solutions in the SMPC (TO-277A) package with the same footprint, the SE50N6x, SE80N6x, SE100N6x, and SE120N6x deliver a 10 % lower profile, 20 % higher current ratings, and 82 % higher forward surge capability.
