SE20Nx, SE30Nx, and SE40Nx Series Automotive-Grade Rectifiers

Vishay's series of automotive-grade, surface-mount standard rectifiers are offered in a power DFN series DFN3820A package with wettable flanks. Providing space-saving, high-efficiency solutions, the 2 A SE20Nx, 3 A SE30Nx, and 4 A SE40Nx are each available with reverse voltages of 200 V, 400 V, and 600 V. Vishay’s DFN3820A’s compact footprint and low profile allow the SE20Nx, SE30Nx, and SE40Nx to make more efficient use of PCB space. 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 SE20Nx, SE30Nx, and SE40Nx offer a 12% lower profile and double the current rating. 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).
