Automotive grade standard rectifiers of the SE series at Rutronik

They are currently the first in the industry to be incorporated into the DFN3820A series of power DFN packages with dimensions of less than 1cm and wettable flanks. The space-saving design of the enclosures allows a more efficient use of the boards with excellent current-carrying capacity. The rectifiers are ideally suited for a wide range of applications in areas such as connectivity, industrial, or consumer.

Vishay Intertechnology introduces three new types of standard surface mount rectifiers for automotive applications. The SE20Nx (2A), SE30Nx (3A), and SE40Nx (4A) offer space-saving solutions with efficiency and operate reliably at operating temperatures of –55 °C and +175 °C.

The DFN3820A package features extremely small dimensions and a particularly low profile, with a compact 3.8 x 2.0mm and a height of 0.88mm. Compared to components in the SMP package (DO-220AA) with the same footprint, the SE20Nx, SE30Nx, and SE40Nx offer a 12 % lower profile while delivering twice the current-carrying capacity.

This thermal performance is due to the optimised copper mass design and advanced die placement technology of the components, enabling operation at higher current ratings. Optimum power line polarity protection and rail-to-rail protection is thus achievable in commercial, industrial, and automotive applications.

Additional benefits:
