Industry's first power DFN series in DFN3820A package

As the industry’s first devices in the compact, Power DFN series DFN3820A package with wettable flanks, the Vishay General Semiconductor 2 A SE20Nx, 3 A SE30Nx, and 4 A SE40Nx surface-mount standard rectifiers make more efficient use of the PCB than competing solutions, while allowing for superior thermal performance and operation at higher current ratings. Compared to devices in the SMP (DO-220AA) package with the same footprint, the AEC-Q101 qualified rectifiers offer a 12 % lower profile and double the current rating. In addition, the SE20Nx, SE30Nx, and SE40Nx 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).
 

The key selling points of the new Standard rectifiers in DFN3820A package are:

• Industry-first Power DFN3820A low profile package
  • small dimensions of 3.8 mm x 2.0 mm with typical height of 0.88 mm
     
• High current and high efficiency
  • current rating from 2 A to 4 A
  • DFN3820A performance more than double under thermal equilibrium conditions compared to SMP (DO-220AA)
     
• AOI-capable package with wettable flanks

The focus applications are:

• Power line polarity protection
• Rail to rail protection in commercial, industrial, and automotive applications

Samples and production quantities of the new surface-mount rectifiers in the DFN3820A package are available now, with lead times of 12 weeks.
