Vishay has introduced three new series of Automotive Grade surface-mount standard rectifiers that are in the low profile DFN3820A package with wettable flanks. Providing space-saving, high-efficiency solutions for power line polarity protection and rail-to-rail protection in commercial, industrial, and automotive applications, the 2A SE20Nx, 3A SE30Nx, and 4A SE40Nx are each available with reverse voltages of 200V, 400V, and 600V.

The first package in Vishay's new Power DFN family, the DFN3820A features a compact 3.8x2.0mm footprint and an extremely low typical height of 0.88mm, allowing the Vishay General Semiconductor rectifiers released today to make more efficient use of PCB space. 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.

Compared to devices in the SMP (DO-220AA) package with the same footprint, the AEC-Q101-qualified SE20Nx, SE30Nx, and SE40Nx offer a 12% lower profile and double the current rating. In addition, the rectifiers offer equivalent or higher current ratings to larger devices in the conventional SMB (DO-214AA) and SMC (DO-214AB) packages, as well as the eSMP series SlimSMA (DO-221AC), SlimSMAW (DO-221AD), SMPA (DO-2212BC), and SMPC (TO-2778A).

Featuring an oxide planar chip junction design, the rectifiers offer a typical reverse leakage current of less than 0.1μA, while their low forward voltage drops down to 0.86V 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. 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.
